So, I started a new chat window, and we were starting to discuss how to put CADI back in place, but you didn’t quite have all the information. So, I started this new chat window, and I went and copied out the part of the conversation we had about CADI. Here it is.

Nice, thanks for pasting the whole thing — that helps a lot.

What’s happening here isn’t actually a NodeSource problem, it’s Caddy’s apt repo blowing up apt update because its GPG key is missing. The NodeSource script just calls apt update under the hood, sees the warning/error, and bails.

So: to get Node 20 on ougway, we either need to:

fix the Caddy repo’s key, or
temporarily disable that repo so apt update can run cleanly

I’ll give you the simplest path first (disable Caddy repo), and then the “proper” fix (re-add the key) in case you want Caddy’s repo working again.

Option A: Temporarily disable the Caddy repo (quick + easy)

List the Caddy sources:

ls /etc/apt/sources.list.d

You’ll likely see something like:

caddy-stable.list

Comment it out or rename it.

Simplest: rename the file so apt ignores it:

sudo mv /etc/apt/sources.list.d/caddy-stable.list 
        /etc/apt/sources.list.d/caddy-stable.list.disabled

Update apt:

sudo apt update

You should no longer see the NO_PUBKEY ABA1F9B8875A6661 error.

Re-run the NodeSource script:

curl -fsSL https://deb.nodesource.com/setup_20.x | sudo -E bash -
sudo apt install -y nodejs

Now it should run cleanly, because apt update isn’t choking on the Caddy repo.

You can leave Caddy’s repo disabled if you don’t care about getting Caddy from that source anymore (or re-enable it later once the key is fixed).

Option B: Fix Caddy’s GPG key (if you actually want that repo working)

If you still want the Caddy repo active, you need to add the missing key for ABA1F9B8875A6661.

On Ubuntu Noble, the modern way is:

sudo mkdir -p /usr/share/keyrings
curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/gpg.key' | 
  sudo gpg --dearmor -o /usr/share/keyrings/caddy-stable-archive-keyring.gpg

Then make sure your Caddy .list file looks something like:

deb [signed-by=/usr/share/keyrings/caddy-stable-archive-keyring.gpg] 
  https://dl.cloudsmith.io/public/caddy/stable/deb/debian any-version main

(If you’re not comfy editing that yet, Option A is totally fine for now.)

Then:

sudo apt update

No more NO_PUBKEY error → NodeSource script will stop complaining.

Quick sanity check after Node install

Once Node 20 is installed:

node -v
npm -v

You want something like:

v20.x.x for node
10.x.x or similar for npm

Then you’re back on track for whatever you were trying to do with Node (GNI, Gemini CLI, etc.).

If you tell me what ls /etc/apt/sources.list.d shows, I can give you the exact mv or edit line tailored to your Caddy file name — but you should be able to do Option A and move forward right away.

ChatGPT — 2025-11-17T00:35:16-08:00 · gpt-5-1-thinking

Perfect, this is exactly the chunk I needed to “remember” what we did.

Let me stitch this together into “how to put Caddy back in place” given where we left off:

There are really two layers to “putting Caddy back”:

Re-enabling the Caddy apt repo (we disabled it with Option A).
Getting the Caddy service + HTTPS certs working again so your browser will allow microphone access.

I’ll walk you through both.

1. Re-enable the Caddy apt repo

If earlier we did Option A, you probably have this:

ls /etc/apt/sources.list.d

You’ll likely see:

caddy-stable.list.disabled

Step 1: Rename it back

sudo mv /etc/apt/sources.list.d/caddy-stable.list.disabled 
        /etc/apt/sources.list.d/caddy-stable.list

Step 2: Re-add/fix the GPG key (so apt stops whining)

Run:

sudo mkdir -p /usr/share/keyrings

curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/gpg.key' | 
  sudo gpg --dearmor -o /usr/share/keyrings/caddy-stable-archive-keyring.gpg

Now make sure /etc/apt/sources.list.d/caddy-stable.list looks roughly like this:

deb [signed-by=/usr/share/keyrings/caddy-stable-archive-keyring.gpg] 
  https://dl.cloudsmith.io/public/caddy/stable/deb/debian any-version main

(If the signed-by=... bit isn’t there, add it.)

Step 3: Update and reinstall Caddy if needed

sudo apt update
sudo apt install caddy

If that runs clean, the Caddy repo is now “back in place” and working.

2. Restore Caddy + HTTPS for your local site

This is the part that gives you HTTPS on ougway.local so the browser will allow mic access.

Earlier, you had:

A cert + key in /etc/ssl/caddy/ougway.local.pem and /etc/ssl/caddy/ougway.local-key.pem
Caddy trying to read them, but failing with permission denied.

Let’s fix that and wire it back up.

Step 1: Fix cert permissions

Check the files:

ls -l /etc/ssl/caddy

You want something like:

-rw-r----- 1 caddy caddy  ... ougway.local.pem
-rw------- 1 caddy caddy  ... ougway.local-key.pem

If they’re owned by root:root (or anything else), fix them:

sudo chown caddy:caddy /etc/ssl/caddy/ougway.local.pem
sudo chown caddy:caddy /etc/ssl/caddy/ougway.local-key.pem

sudo chmod 640 /etc/ssl/caddy/ougway.local.pem
sudo chmod 600 /etc/ssl/caddy/ougway.local-key.pem

Key idea: the caddy user must be able to read both files, and the key should not be world-readable.

Step 2: Put the Caddyfile back the way we want it

Open /etc/caddy/Caddyfile:

sudo nano /etc/caddy/Caddyfile

A minimal Caddyfile for a local HTTPS reverse proxy to something like OpenWebUI or Diffusers looks like this (adjust the port to whatever your app uses):

ougway.local {
    tls /etc/ssl/caddy/ougway.local.pem /etc/ssl/caddy/ougway.local-key.pem

    # If OpenWebUI (or whatever) is on port 8080:
    reverse_proxy 127.0.0.1:8080
}

If your app is on a different port (3000, 7860, etc.), just change 8080 accordingly.

Save and exit.

Step 3: Enable and start Caddy again

sudo systemctl daemon-reload
sudo systemctl enable caddy
sudo systemctl restart caddy
sudo systemctl status caddy --no-pager -l

You want to see it active (running), not failed or permission denied.

If you still see a permissions error, it will almost certainly mention the key path again—then it’s just a matter of adjusting chown/chmod until caddy can read it.

Step 4: Test from your browser

On any machine on your LAN that can resolve ougway.local to your box:

Visit: https://ougway.local
The browser may show a warning (since it’s a local/mkcert cert) — accept/trust it.
Once loaded over HTTPS, your mic-based features (for OpenWebUI, etc.) should be available again.

Quick recap

To “put Caddy back in place” based on what we did before:

Undo the repo disable:
Rename caddy-stable.list.disabled → caddy-stable.list.
Add the Cloudsmith GPG key.
sudo apt update && sudo apt install caddy.
Restore TLS + proxy:
Ensure /etc/ssl/caddy/ougway.local*.pem are owned by caddy:caddy and not world-readable.
Restore a simple ougway.local { tls ...; reverse_proxy ... } block in /etc/caddy/Caddyfile.
systemctl enable --now caddy and confirm it’s running.

If you want, you can paste the current contents of:

ls -l /etc/ssl/caddy
/etc/caddy/Caddyfile
and the last few lines of sudo systemctl status caddy --no-pager -l

and I’ll line-edit exactly what to change.

Darren — 2025-11-17T00:40:32-08:00

First, how do I get to look at this? I don’t see Etsy in my file manager list.
/etc/apt/sources.list.d/caddy-stable.list

[USER]@[HOST]:~/Desktop$ ls -l /etc/ssl/caddy
ls: cannot open directory ‘/etc/ssl/caddy’: Permission denied
[USER]@[HOST]:~/Desktop$

ChatGPT — 2025-11-17T00:40:32-08:00 · gpt-5-1

Good — both of those behaviors make sense on Linux, and here’s how to handle each one cleanly.

✅ 1. “How do I look at /etc/apt/sources.list.d/caddy-stable.list?”

Your file manager won’t show system folders like /etc/apt/... unless you open it as root (which Ubuntu disables by default).

So you view/edit these files from the terminal, like this:

View the file:

cat /etc/apt/sources.list.d/caddy-stable.list

Or open it in a text editor (recommended):

sudo nano /etc/apt/sources.list.d/caddy-stable.list

That opens it directly, no file manager needed.

✅ 2. “ls: cannot open directory ‘/etc/ssl/caddy’: Permission denied”

Correct — that directory is restricted to root, because it contains cryptographic private keys.

To view its contents:

sudo ls -l /etc/ssl/caddy

Using sudo is required to see inside that folder.

🚀 Here’s what to do next (step-by-step)

Step A: List the Caddy repo file

ls /etc/apt/sources.list.d

Look for:

caddy-stable.list
caddy-stable.list.disabled

Tell me what appears.

Step B: Look inside the SSL folder

sudo ls -l /etc/ssl/caddy

Paste the output so I can see what cert/key files are there and whether ownership looks wrong.

If you’d like, paste both outputs:

ls /etc/apt/sources.list.d
sudo ls -l /etc/ssl/caddy

Once I see those, I’ll tailor the exact commands to fully restore Caddy and HTTPS.

Perfect — this tells me everything I need.
Your Caddy repo is already re-enabled, and the .list file is valid and correct.

Now we just need to:

Make sure the GPG key exists (or reinstall it).
Check the Caddy cert folder.
Restart Caddy cleanly.

Let’s proceed step-by-step.

✅ STEP 1 — Reinstall the Caddy GPG Key (safe even if it exists)

Run this exactly:

sudo mkdir -p /usr/share/keyrings

curl -1sLf "https://dl.cloudsmith.io/public/caddy/stable/gpg.key" | 
  sudo gpg --dearmor -o /usr/share/keyrings/caddy-stable-archive-keyring.gpg

If it succeeds silently → you’re good.

Then:

sudo apt update

If there is no NO_PUBKEY error, then the repo is 100% fixed.

Tell me if apt shows any errors here.

✅ STEP 2 — View contents of the SSL directory (requires sudo)

Earlier you ran:

ls: cannot open directory '/etc/ssl/caddy': Permission denied

Correct — the folder requires root.

Now run:

sudo ls -l /etc/ssl/caddy

Paste the output.

I need to see:

names of the certs
their owners
their permissions

This will tell me exactly why Caddy was previously failing with:

permission denied /etc/ssl/caddy/ougway.local-key.pem

Once you paste that output, I’ll tell you EXACTLY what to fix

There are only two possibilities:

A) The files exist but are owned by root → we fix with `chown caddy:caddy`

B) The files are missing → we regenerate them with mkcert

…or with OpenSSL if restoring mkcert is needed.

Either way, I can repair it in < 60 seconds once I see the listing.

Go ahead and run:

sudo apt update
sudo ls -l /etc/ssl/caddy

-rw-r—– 1 root caddy 1521 Nov 14 23:26 ougway.local.pem
[USER]@[HOST]:~/Desktop$

So one other question with this is I would also like to open the web page for the diffuser from other machines on my LAN but it doesn’t seem to allow me at the moment.

ChatGPT — 2025-11-17T00:44:48-08:00 · gpt-5-1

Great — this confirms the exact problem and the fix is easy.

Your certs have this ownership:

-rw-r----- 1 root caddy  ougway.local-key.pem
-rw-r----- 1 root caddy  ougway.local.pem

This means:

Group = caddy → OK
Owner = root → NOT OK
Permissions = 640 → NOT OK for private key

Caddy runs as user caddy, so it cannot read a file owned by root unless the group permissions are more open — but for private keys, group-read must be restricted to only caddy.

So we fix ownership + permissions like this:

✅ STEP 1 — Fix ownership of both cert files

Run:

sudo chown caddy:caddy /etc/ssl/caddy/ougway.local.pem
sudo chown caddy:caddy /etc/ssl/caddy/ougway.local-key.pem

✅ STEP 2 — Fix permissions (private key must NOT be group-readable)

Recommended:

sudo chmod 640 /etc/ssl/caddy/ougway.local.pem
sudo chmod 600 /etc/ssl/caddy/ougway.local-key.pem

This makes:

cert: readable by caddy
key: readable only by caddy

✅ STEP 3 — Restart Caddy

sudo systemctl restart caddy
sudo systemctl status caddy --no-pager -l

You should now see:

active (running)

If you see that → your HTTPS is repaired.

🚀 NEXT QUESTION: “I want to open the Diffuser webpage from other machines on my LAN”

Right now, your app (Diffusers / A1111 API / OpenWebUI back-end?) is probably binding to localhost only, like:

127.0.0.1:xxxx

This means the service is ONLY accessible from the PC itself.

To make it accessible LAN-wide through Caddy, you have two options:

OPTION A (best): Serve it through Caddy on HTTPS

In your /etc/caddy/Caddyfile, you probably have:

ougway.local {
    tls /etc/ssl/caddy/ougway.local.pem /etc/ssl/caddy/ougway.local-key.pem
    reverse_proxy 127.0.0.1:8080
}

If the diffuser UI is on a different port, change it:

A1111 web UI = often 7860
OpenWebUI = often 3000, sometimes 8080
Diffusers API = depends on your setup

Whatever port it is, plug it in here.

Example:

ougway.local {
    tls /etc/ssl/caddy/ougway.local.pem /etc/ssl/caddy/ougway.local-key.pem
    reverse_proxy 127.0.0.1:7860
}

Then from ANY machine on your LAN:

https://ougway.local

…will open your diffuser interface.

You do NOT need to expose that port directly.

OPTION B: Run the app on 0.0.0.0 instead of 127.0.0.1

For example:

python -m diffusers.api --host 0.0.0.0

That makes it accessible on:

http://192.168.x.x:YOUR_PORT

But this is not secure, and browsers will still block microphone access due to no HTTPS.

This is why Caddy is the right solution.

👉 What I need from you next

Tell me which app/port you want exposed to the LAN:

OpenWebUI (web interface)
Automatic1111
Diffusers API
Gemini / GNI Node server
Something else?

And paste this:

sudo ss -tulnp

Then I’ll:

verify which ports your services are actually listening on
build an exact, correct, clean Caddyfile for you
make LAN access work
keep HTTPS so your mic feature works

You’re 95% done — just need the port details.

Darren — 2025-11-17T00:46:44-08:00

A1111 web UI = often 7860 yes this one

ChatGPT — 2025-11-17T00:46:44-08:00 · gpt-5-1

Perfect — Automatic1111 (A1111) normally runs on port 7860, binds to 127.0.0.1, and does not provide HTTPS by itself.
Using Caddy is the correct way to publish it to your LAN securely and get microphone access working.

Below is the exact configuration you need.

✅ STEP 1 — Update your Caddyfile for A1111

Open:

sudo nano /etc/caddy/Caddyfile

Replace the contents (or add a new block) with:

ougway.local {
    tls /etc/ssl/caddy/ougway.local.pem /etc/ssl/caddy/ougway.local-key.pem

    # Forward HTTPS traffic to Automatic1111
    reverse_proxy 127.0.0.1:7860
}

Save: CTRL + O, then exit CTRL + X.

✅ STEP 2 — Restart Caddy

sudo systemctl restart caddy
sudo systemctl status caddy --no-pager -l

Look for:

active (running)

If it’s running → good.

✅ STEP 3 — Access A1111 from other machines on your LAN

From ANY device on the LAN, open:

https://ougway.local

✔ That will show your A1111 web UI
✔ Over HTTPS
✔ Mic access (if the browser needs it for extensions) will work
✔ DNS should resolve normally if you have mDNS enabled (Ubuntu does by default)

If the device cannot resolve ougway.local, use:

https://ougway.local.local

OR worst-case:

https://192.168.x.x

(with a browser trust prompt because cert is for ougway.local, not IP)

OPTIONAL (but recommended for clean operation)

Ensure A1111 binds to localhost (the default) so it’s not exposed without HTTPS.

If you have a manual launch script for A1111, make sure it does NOT use:

--listen
--listen-port
--share

Unless explicitly needed.

Normal safe launch:

python launch.py

or your preferred script — as long as it binds to 127.0.0.1, we’re good.

🟦 If `ougway.local` doesn’t resolve on other machines

Check whether mDNS is running:

On Ubuntu box:

systemctl status avahi-daemon

If inactive:

sudo systemctl enable --now avahi-daemon

Then ougway.local will resolve automatically from Windows, Mac, Linux, iOS, Android.

If you want, I can generate:

A full Caddyfile
A systemd service wrapper for A1111
An optional password-protected gateway
A LAN-only access mode
A combined A1111 + Diffusers + OpenWebUI multi-route setup

Just tell me.

Do you want A1111 to be the only thing behind HTTPS,
or do you want:

https://ougway.local/a1111
https://ougway.local/openwebui
https://ougway.local/diffuser
etc.

We can build a full multi-service gateway.

Nice, that error is actually very informative:

Error: adapting config using caddyfile: ambiguous site definition: ougway.local

That means:
📌 You have ougway.local defined more than once in /etc/caddy/Caddyfile.
Caddy refuses to start when the same site label is duplicated.

We just need to make sure there’s only one ougway.local { ... } block.

1️⃣ Find the duplicate `ougway.local` blocks

Run:

sudo grep -n 'ougway.local' /etc/caddy/Caddyfile

You’ll see 2 or more lines with ougway.local on them — that’s the problem.

Now open the file to fix it:

sudo nano /etc/caddy/Caddyfile

2️⃣ Clean it up: keep ONE block, delete or comment the others

Inside the Caddyfile, you probably have something like:

ougway.local {
    # ... old stuff here ...
}

# later in the file

ougway.local {
    tls /etc/ssl/caddy/ougway.local.pem /etc/ssl/caddy/ougway.local-key.pem
    reverse_proxy 127.0.0.1:7860
}

Caddy sees two separate site definitions with the same label ougway.local → ambiguous.

Easiest fix (for now):

Option A – Only keep the new one we just made

Find the earlier ougway.local { ... } block.
Either:
– delete that whole block, or
– comment it out by putting # in front of each line, like:

caddyfile # ougway.local { # # old config # }

Leave only one active block that looks like:

caddyfile ougway.local { tls /etc/ssl/caddy/ougway.local.pem /etc/ssl/caddy/ougway.local-key.pem reverse_proxy 127.0.0.1:7860 }

Save (Ctrl+O, Enter) and exit (Ctrl+X).

3️⃣ Restart Caddy

sudo systemctl restart caddy
sudo systemctl status caddy --no-pager -l

You want:

Active: active (running)

If it’s running, Caddy is happy and:

https://ougway.local should now open the A1111 UI
from this machine and from other machines on your LAN (as long as ougway.local resolves).

4️⃣ Test from another machine on the LAN

On another PC/phone on your network, try:

https://ougway.local

You may get a “not secure / self-signed” warning the first time — accept/trust it.

If ougway.local doesn’t resolve, we can:

use https://<your-LAN-IP> temporarily, or
tweak mDNS / hosts file so the name works cleanly.

If you want, you can paste the full contents of /etc/caddy/Caddyfile and I’ll hand-edit it into a clean, multi-service config for you (A1111 now, diffuser/OpenWebUI later) with zero ambiguity.

Darren — 2025-11-17T00:52:44-08:00

ougway.local {
tls /etc/ssl/caddy/ougway.local.pem /etc/ssl/caddy/ougway.local-key.pem
reverse_proxy http://127.0.0.1:8080
}

I removed the one we just made that wrecked it….which was…
ougway.local {
tls /etc/ssl/caddy/ougway.local.pem /etc/ssl/caddy/ougway.local-key.pem
reverse_proxy 127.0.0.1:7860
}

Dont we need both ports though?

Great — now we’re at the real design question:

“Don’t we need both ports though?”

Yes, but not as two ougway.local blocks.
Caddy does not allow duplicate site labels.

Instead, you have one ougway.local { … } block,
and inside it you create routes for each service.

This is the correct, clean, future-proof way to host multiple services behind one HTTPS domain.

✅ The Right Way: One domain, multiple paths

Here is exactly how to serve:

OpenWebUI (8080)
A1111 (7860)

under the same domain https://ougway.local, cleanly and safely.

Replace your entire Caddyfile with this:

ougway.local {
    tls /etc/ssl/caddy/ougway.local.pem /etc/ssl/caddy/ougway.local-key.pem

    # Root route (default) goes to OpenWebUI on 8080
    reverse_proxy / http://127.0.0.1:8080

    # Route /a1111 to Automatic1111 on 7860
    handle_path /a1111* {
        reverse_proxy http://127.0.0.1:7860
    }
}

Save and restart:

sudo systemctl restart caddy
sudo systemctl status caddy --no-pager -l

If you see active (running) → success.

✅ How to access the services now

OpenWebUI

https://ougway.local

Automatic1111

https://ougway.local/a1111

Browser will use HTTPS → microphone permissions will work.

LAN clients can access both.

Why this works

Caddy routing rules say:

/ (root) → send traffic to OpenWebUI on 8080
/a1111 → strip the prefix and reverse proxy to A1111 on 7860

This avoids:

duplicate host definitions
port conflicts
needing multiple certificates
needing multiple DNS names

And it gives you a clean portal for future services, e.g.:

/diffusers
/gni
/stablediffusionxl
/openwebui2
/webui2

…all under one domain.

If you want even cleaner URLs

I can also set up subdomains:

a1111.ougway.local
ui.ougway.local
diffuser.ougway.local

All with the same certificate and same LAN accessibility.

Just say the word.

If you’re ready, paste:

sudo systemctl status caddy --no-pager -l

after you restart — I’ll verify it’s perfect.

Well, for whatever reason, it works if I use local links on the local machine. So, in other words, OpenWebUI will open, however, it failed to load the model again, stating that it was out of memory somewhere. And when I try to access the website from an external machine, I get 500 colon internal error. And on the diffuser web page, it just comes up blank. However, hmm.

ChatGPT — 2025-11-17T01:04:27-08:00 · gpt-5-1-thinking

Right, this all fits together:

✅ Caddy / HTTPS / routing are basically fine.
🔴 What’s breaking things (and causing the 500s from other machines) is the CUDA out-of-memory crash in the backend (A1111 / SD-WebUI).
When the backend dies with OOM, Caddy has nothing to talk to → “500 internal error” to the browser. Local vs remote doesn’t matter; it’s just more obvious remotely.

Let’s untangle it step-by-step.

1. What the error is actually saying

Key bit from the traceback:

torch.cuda.OutOfMemoryError: CUDA out of memory. Tried to allocate 20.00 MiB.
GPU 0 has a total capacty of 11.63 GiB of which 21.19 MiB is free.
Process 1437653 has 6.01 GiB memory in use. Including non-PyTorch memory, this process has 5.24 GiB memory in use.
Of the allocated memory 5.03 GiB is allocated by PyTorch...

Translated:

Your GPU has ~11.6 GB usable VRAM.
Only 21 MB is free when SD-WebUI is trying to allocate another 20 MB.
There’s already a big chunk (6 GB) in use by this process, and even more by something else.

So when A1111 or whatever tries to finish loading the checkpoint / attention layers, boom → OOM → process crashes → Caddy sees upstream die → 500 to client.

This is why:

OpenWebUI opens (UI itself uses almost no VRAM),
but model load fails,
and from another machine you just see “500 internal error” or blank page.

2. First sanity check: what’s hogging VRAM?

On ougway, run:

nvidia-smi

You’ll see a table with processes and memory usage.

If you see more than one heavy AI process (e.g., OpenWebUI, A1111, diffusers, some other model server), they’re competing for GPU memory.

Rule of thumb for your card:
You really want only one big model on the GPU at a time, or run the others in CPU/low-VRAM mode.

3. Quick “unstick” sequence

A. Kill stuck GPU processes

If you see old/stuck processes in nvidia-smi, you can:

sudo kill -9 <PID>

or, if you want to nuke all Python GPU jobs at once:

sudo pkill -9 python

(Do this only if you’re okay killing any Python-based tools that are running.)

Re-run:

nvidia-smi

and confirm VRAM is mostly free before restarting A1111/OpenWebUI.

4. Start SD-WebUI / A1111 in a more VRAM-friendly way

For A1111 (stable-diffusion-webui), use medvram or lowvram, and optionally xformers.

From your A1111 folder:

cd [HOME]/ai/stable-diffusion-webui

# Example: safer VRAM settings
python launch.py --medvram --xformers

If that still OOMs, try:

python launch.py --lowvram --xformers

Also, note this line in your stack trace:

modules/sd_disable_initialization.py

That’s an extension / script that changes how layers are initialized. If memory is really tight, you can temporarily disable that extension:

In the extensions folder, find anything related to sd_disable_initialization and move it out or disable it in the WebUI,
Then restart A1111.

Fewer hacks/extensions = less VRAM burn.

5. Don’t double-load big models

Given that:

OpenWebUI can host models itself and/or
A1111 is also loading a full SD model,

you can easily end up with two 5–6 GB models on the same GPU.

Pick one of these approaches:

Option 1 – A1111 only on GPU

Run A1111 on GPU (launch.py --medvram etc.).
Configure OpenWebUI to use either:
a smaller model, or
CPU, or
don’t run a model there at all (just use it as UI for other stuff).

Option 2 – OpenWebUI only on GPU

Run the big model in OpenWebUI.
Don’t start A1111 at the same time, or run A1111 with --use-cpu or similar if you need it for something smaller.

The main point: only one heavyweight GPU model at a time unless you’re very careful.

6. Why external access shows 500 / blank

Caddy is just your HTTPS bouncer.

Browser (remote) → Caddy (https://ougway.local/...) → backend (A1111/OpenWebUI).
Backend crashes on OOM → Caddy can’t get a response → returns 500 (or blank page) to the client.

Once you:

Free VRAM,
Restart the backend with --medvram/--lowvram,
Avoid double-loading large models,

…the 500s will disappear, because the backend will actually stay alive.

7. Concrete sequence to try right now

On ougway:

# 1. See what's on the GPU
nvidia-smi

# 2. Kill stale GPU-hungry processes if needed
sudo pkill -9 python

# 3. Restart A1111 safely
cd [HOME]/ai/stable-diffusion-webui
python launch.py --medvram --xformers

# 4. Check Caddy is still happy
sudo systemctl status caddy --no-pager -l

Then:

On ougway, visit: https://ougway.local/a1111
From another machine, visit: https://ougway.local/a1111

If you can get the A1111 UI up and load a model without OOM, the 500 problem should be gone as well.

If you tell me roughly what you want the GPU to be dedicated to (OpenWebUI only, A1111 only, or both in some balance), I can lay out a minimal “profile”:

which services to auto-start,
what launch flags to use,
and how to keep everything reachable via Caddy without stepping on VRAM.

Darren — 2025-11-17T01:12:23-08:00

Okay, well, this sample looks like it was stupid user tricks. Apparently, I tried to double-load standard diffusion. It was already running in another window that I didn’t notice. Right now, I’ve noticed also that depending on the diffusers that are loaded, or the checkpoint stuff, so in other words, version 1.5 pruned EMA-only save tensors take up a lot less memory than any of the other three that are in there. So, if I’m going to be generating images, I’m more than likely not going to be doing OpenWebUI stuff at the same time, is what this is telling me, yes. I could probably get away with running a model right now that was of a smaller nature, because it’s only using about 2.6 gig of that VRAM. So, for instance, if I generated an image right now, copper torus on a wooden table, let’s see what we get. Well, my current usage, it did spike to 6 megabyte for a second there. So, if I’m going to be generating images, I need to not be using anything else at the same time, apparently. Okay.However, that’s not helping with any of the stuff from accessing this with the remote machine. So, why don’t we just, for the sake of the argument, I’m going to restart this machine, and see if I can just access OpenWebUI.

ChatGPT — 2025-11-17T01:12:52-08:00 · gpt-5-1-thinking

Yeah, that all tracks perfectly: you basically discovered the rule of thumb for your box—

If you’re doing heavy SD image gen, don’t also try to run a big LLM on the same GPU.

And your observations about 1.5 pruned EMA-only vs the others are exactly what I’d expect: smaller checkpoints = less VRAM pressure = fewer explosions.

Let’s split this into two things:

1. Sanity check on your conclusions (VRAM / usage)

You’re reading it right:

If SD-WebUI is spiking VRAM from ~2.6 GB up to ~6–7 GB while generating,
And another model (OpenWebUI, diffusers, etc.) is loaded on the GPU at the same time,

…you’re in “very easy to OOM” territory.

So for stable, no-drama operation:

When you’re doing serious SD work → run SD-WebUI only on the GPU, keep OpenWebUI either:
not running, or
running but not using a GPU model (or using a tiny one).
When you’re doing chat / coding help / etc. via OpenWebUI → you can:
stop SD-WebUI, or
run SD-WebUI but don’t load a heavy model there.

You can absolutely juggle both on that card, just not two fat models fully loaded at once.

2. After the reboot: how to check OpenWebUI from LAN

Since you’re about to restart anyway, here’s the exact checklist to walk through when it comes back up.

Step 1: Confirm Caddy is up

On ougway:

sudo systemctl status caddy --no-pager -l

You want active (running).
If it’s failed, we look at the error message, but it should be happy now.

Step 2: Confirm OpenWebUI is running on 8080

However you usually start OpenWebUI (service, docker, or python main.py), get it running, then check:

ss -tulnp | grep 8080

You should see something like:

LISTEN ... 127.0.0.1:8080 ... python

And from ougway itself, test:

https://ougway.local

If that loads OpenWebUI → Caddy + TLS + proxy are all good.

Step 3: Test from the remote machine

On the other machine:

Try:
text https://ougway.local
If that fails with a name resolution error, try IP:
text https://<ougway-LAN-IP>
(Your browser will complain because the cert is for ougway.local, but it should still show the page if you click through the warning.)

What should happen:

If OpenWebUI is up and not crashing → no more 500s.
If you still get 500 on the remote but it works locally, that usually means:
the backend crashed again (check nvidia-smi and the OpenWebUI logs), or
the Caddyfile is pointing to the wrong port.

3. If it still acts weird after reboot

If, after reboot, you see any of these:

https://ougway.local works on ougway but not on the other machine
remote still gets 500 / blank page
OpenWebUI doesn’t come up even locally over HTTPS

then grab these three outputs on ougway:

sudo systemctl status caddy --no-pager -l
ss -tulnp | grep 8080
cat /etc/caddy/Caddyfile

Paste them, and I’ll adjust exactly what’s needed so:

OpenWebUI is reachable at https://ougway.local from any box on your LAN,
SD-WebUI is reachable at https://ougway.local/a1111 when it’s running,
and you’re not stepping on your GPU when you don’t mean to.

Darren — 2025-11-17T01:23:20-08:00

[USER]@[HOST]:~/Desktop$ ss -tulnp | grep 8080
tcp LISTEN 0 2048 0.0.0.0:8080 0.0.0.0:*
[USER]@[HOST]:~/Desktop$

Okay, so it’s the HTTPS that’s broken. OpenLab UI lets me in if I use localhost 8080, and on my remote machine it lets me in if I use the LAN IP address, but it gives me a 500 error if I try to HTTPS to ugui-local.

ChatGPT — 2025-11-17T01:24:13-08:00 · gpt-5-1-thinking

Gotcha, that helps narrow it down a lot:

OpenWebUI works:
http://localhost:8080 on ougway ✅
http://<LAN-IP>:8080 from another machine ✅
But https://ougway.local → 500 Internal Error ❌

So: backend is fine, HTTPS proxy is what’s unhappy. That’s squarely in Caddy land.

Let’s do this in two steps:
1) sanity-check Caddy logs,
2) simplify the Caddy config so there’s nothing subtle going wrong.

1. Check what Caddy is actually complaining about

On ougway, run:

sudo systemctl status caddy --no-pager -l

Then:

sudo journalctl -u caddy --no-pager | tail -n 40

That second one is the important one — it’ll show what happens when you hit https://ougway.local.

2. Use a dead-simple Caddyfile as a test

Right now you have something like:

ougway.local {
    tls /etc/ssl/caddy/ougway.local.pem /etc/ssl/caddy/ougway.local-key.pem
    reverse_proxy http://127.0.0.1:8080
}

Let’s keep the host name, but make the block absolutely minimal and explicit.

Edit the Caddyfile:

sudo nano /etc/caddy/Caddyfile

Change the ougway.local block to exactly this:

ougway.local {
    tls /etc/ssl/caddy/ougway.local.pem /etc/ssl/caddy/ougway.local-key.pem

    reverse_proxy 127.0.0.1:8080
}

Note: no http:// in the proxy line (Caddy figures that out), just a clean upstream.

Save and restart:

sudo systemctl restart caddy
sudo systemctl status caddy --no-pager -l

You want active (running).

3. Test the upstream behavior directly (host header check)

Let’s make sure OpenWebUI doesn’t freak out when the Host header is ougway.local.

On ougway, run:

curl -H "Host: ougway.local" http://127.0.0.1:8080

If you see HTML for OpenWebUI → good, it tolerates that host.
If you see a 500 here, that means OpenWebUI itself is returning 500 when the host isn’t localhost or <LAN-IP>.

That would explain why Caddy gives 500 even though plain http://localhost:8080 works.

4. LAN tests to isolate where it breaks

After restarting Caddy with the minimal config:

On ougway itself:
– Try https://ougway.local in the browser.
On the remote machine:
– Try https://ougway.local
– If that fails, try https://<LAN-IP>

(Your browser will warn about the cert name mismatch on the IP, but it still shouldn’t be a 500; it should show the same page.)

If:

https://<LAN-IP> works but https://ougway.local gives 500, we’re dealing with something host-name specific.
Both give 500, but http://<LAN-IP>:8080 is fine → Caddy’s logs will tell us exactly why.

Likely scenarios (so you know what we’re looking for)

Based on what you described, the 500 is probably one of these:

OpenWebUI doesn’t like the Host header ougway.local and returns 500.
– curl -H "Host: ougway.local" http://127.0.0.1:8080 will confirm.
Caddy is failing to connect to the upstream for some reason (less likely since direct 127.0.0.1:8080 works).
– Logs will show something like “dial tcp 127.0.0.1:8080: connect: connection refused”.
Some subtle config issue in the Caddyfile (we’re removing that possibility with the bare-bones config above).

What I need from you next

After you try the steps:

Output of:

bash sudo systemctl status caddy --no-pager -l sudo journalctl -u caddy --no-pager | tail -n 40 curl -H "Host: ougway.local" http://127.0.0.1:8080

And what you see when you hit:
– https://ougway.local on ougway,
– https://ougway.local and https://<LAN-IP> on the remote machine.

Once I see those, I can tell you exactly whether it’s Caddy, DNS/hostname handling, or OpenWebUI being picky — and we’ll tweak the config accordingly.

ChatGPT — 2025-11-17T01:27:58-08:00 · gpt-5-1-thinking

Nice, those logs are super clear and actually tell us a lot.

What the logs say

Caddy is healthy:

Active: active (running)
...
"server running","name":"srv0","protocols":["h1","h2","h3"]

The only error in the log is this:

dial tcp 127.0.0.1:7860: connect: connection refused
...
"uri":"/a1111"
"status":502

That means:

Someone (you, from [LOCAL HOST]) hit https://ougway.local/a1111
Caddy tried to proxy that to 127.0.0.1:7860
But nothing is listening on 7860 → connection refused → 502 Bad Gateway

So:

HTTPS itself is not broken.
The only thing failing right now is the /a1111 route when A1111 is not running.

If you go to https://ougway.local/a1111 while A1111 is stopped, you should see exactly that 502 behavior.

Where that leaves us

Given what you’ve told me so far:

http://localhost:8080 works on ougway ✅
http://<LAN-IP>:8080 works from the remote machine ✅
Caddy is up and listening on 443 ✅
The log shows only errors for /a1111 → proxy to 7860 ❌ (A1111 not running).

So right now the state is probably:

https://ougway.local → should go to 8080 / OpenWebUI
https://ougway.local/a1111 → will 502 unless A1111 is running on 7860

If you’re currently not running A1111, any 500/502 you see when testing /a1111 is totally expected and not a Caddy bug.

Quick mental checklist

Right now, assuming your Caddyfile is roughly:

ougway.local {
    tls /etc/ssl/caddy/ougway.local.pem /etc/ssl/caddy/ougway.local-key.pem

    # OpenWebUI
    reverse_proxy 127.0.0.1:8080

    # A1111 (optional)
    handle_path /a1111* {
        reverse_proxy 127.0.0.1:7860
    }
}

Then:

Use OpenWebUI at:
https://ougway.local (Caddy → 127.0.0.1:8080)
Use A1111 at:
https://ougway.local/a1111 (Caddy → 127.0.0.1:7860)
only when A1111 is actually running

If you’re mainly focused on OpenWebUI right now and don’t care about A1111 through HTTPS yet, you can even comment out the /a1111 bit to eliminate the noise:

ougway.local {
    tls /etc/ssl/caddy/ougway.local.pem /etc/ssl/caddy/ougway.local-key.pem
    reverse_proxy 127.0.0.1:8080
}

Then restart:

sudo systemctl restart caddy

and both:

https://ougway.local (from ougway), and
https://ougway.local (from the LAN machine)

should just be pure OpenWebUI, no A1111 routing at all, no 502s.

If you want both services behind HTTPS, we can keep /a1111 in the Caddyfile, but the key point is: seeing dial tcp 127.0.0.1:7860: connect: connection refused simply means A1111 wasn’t running, not that HTTPS is broken.

Darren — 2025-11-17T01:33:53-08:00

yes everything works if I go to local ip address’s however ougway.local gets me a webpage with a non retreivable icon in center that does not have but a place holder to tell you its there which I think are these same results.

[USER]@[HOST]:~/Desktop$ curl -H “Host: ougway.local” http://127.0.0.1:8080

Open WebUI

[USER]@[HOST]:~/Desktop$

ChatGPT — 2025-11-17T01:34:52-08:00 · gpt-5-1-thinking

Nice, that curl output is actually super reassuring — it tells us a lot.

curl -H "Host: ougway.local" http://127.0.0.1:8080 is returning the full OpenWebUI HTML, including:
/static/splash.png
/static/loader.js
/_app/... modules

So:

OpenWebUI is totally fine with the Host: ougway.local header.
The backend is behaving.
The “blank page / icon placeholder” you see in the browser is now a front-end problem (JS / assets not loading), not a proxy or DNS problem.

What you’re seeing — splash screen with “something should be here” but nothing loading — is exactly what happens when the JS app fails to start or its static assets don’t load.

Let’s tighten the Caddy side so OpenWebUI gets the right headers, then verify assets over HTTPS.

1. Make the Caddyfile explicit for OpenWebUI

Let’s give OpenWebUI the usual proxy headers it expects.

Edit the file:

sudo nano /etc/caddy/Caddyfile

Make the ougway.local block look like this (for now, I’ll ignore A1111 to keep it simple; we can add it back after this works):

ougway.local {
    tls /etc/ssl/caddy/ougway.local.pem /etc/ssl/caddy/ougway.local-key.pem

    reverse_proxy 127.0.0.1:8080 {
        header_up Host {host}
        header_up X-Real-IP {remote_host}
        header_up X-Forwarded-For {remote_host}
        header_up X-Forwarded-Proto https
    }
}

Save (Ctrl+O, Enter), exit (Ctrl+X), then:

sudo systemctl restart caddy
sudo systemctl status caddy --no-pager -l

Make sure it’s still active (running).

Those headers make sure OpenWebUI knows:

what host was requested,
what the original client IP was,
and that the real scheme is https (even though Caddy is talking http to 8080).

Some apps get picky about that.

2. Check that static assets work via HTTPS

From ougway, test through Caddy:

# HTML (we know this works, but just for completeness)
curl -k https://ougway.local/

# Check one static asset
curl -kI https://ougway.local/static/splash.png

# Check loader JS
curl -kI https://ougway.local/static/loader.js

You should see HTTP/2 200 (or HTTP/1.1 200) for those -I head requests.

If those are 200s, then:

Caddy is correctly proxying all the things the page references.
The HTML + JS + images are all available over HTTPS.

At that point, if the browser still shows the splash with a broken/missing icon, it’s almost certainly:

the browser blocking something,
or a stale service worker / cache from earlier attempts.

3. Browser side: what to do

On the machine where https://ougway.local looks “stuck”:

Open DevTools:
– Firefox: F12 → Console and Network tabs.
Hard reload:
– Ctrl+Shift+R (bypass cache).
Watch Network:
– Look for red entries to /static/... or /_app/...
– See what status codes they get (404? 500? blocked?).

But you already basically tested that with curl: if curl -kI https://ougway.local/static/splash.png is 200, the browser should be able to fetch it too (once it trusts the cert).

If you haven’t already done it:

When you first go to https://ougway.local, the browser will warn you the cert is not trusted (mkcert/local CA).
You must click through and trust/accept it.
If you don’t fully trust it, some resources may be blocked.

4. LAN vs local IP behavior (why HTTP works but HTTPS looks weird)

Right now:

http://<LAN-IP>:8080 → works fine (no TLS, raw OpenWebUI).
https://ougway.local → HTML loads (as curl shows), but the app looks stuck at the splash.

That means:

the only differences between the two are:
TLS layer,
Host (ougway.local vs IP),
and proxy headers.

We’ve now:

Confirmed Host: ougway.local is fine for the backend.
Added the canonical proxy headers (X-Forwarded-Proto, etc.).
Verified Caddy is healthy.

Once assets are confirmed 200 over HTTPS via curl -kI, the last piece is the browser’s trust + cache.

5. If you want A1111 back later

Once OpenWebUI over https://ougway.local is behaving, you can re-add A1111 like this:

ougway.local {
    tls /etc/ssl/caddy/ougway.local.pem /etc/ssl/caddy/ougway.local-key.pem

    # Root: OpenWebUI
    reverse_proxy 127.0.0.1:8080 {
        header_up Host {host}
        header_up X-Real-IP {remote_host}
        header_up X-Forwarded-For {remote_host}
        header_up X-Forwarded-Proto https
    }

    # A1111: only when running on 7860
    handle_path /a1111* {
        reverse_proxy 127.0.0.1:7860
    }
}

Then:

https://ougway.local → OpenWebUI
https://ougway.local/a1111 → SD WebUI (when it’s actually running)

TL;DR what to do next

Update Caddyfile with the reverse_proxy { header_up ... } block.
Restart Caddy, make sure it’s running.
From ougway, run:

bash curl -kI https://ougway.local/static/splash.png curl -kI https://ougway.local/static/loader.js

On the remote machine:
– Trust the ougway.local certificate if prompted.
– Hard reload (Ctrl+Shift+R).
– See if the full OpenWebUI UI appears instead of just the splash.

If you want, you can paste the results of those curl -kI commands; if anything there isn’t a 200, I can pinpoint exactly which piece is still misbehaving.

Darren — 2025-11-17T01:36:45-08:00

ougway.local {
tls /etc/ssl/caddy/ougway.local.pem /etc/ssl/caddy/ougway.local-key.pem

# Root route (default) goes to OpenWebUI on 8080
reverse_proxy / http://127.0.0.1:8080

# Route /a1111 to Automatic1111 on 7860
handle_path /a1111* {
    reverse_proxy http://127.0.0.1:7860
}

}

u used http:// in these but not in the one i’m seeing is that a problem?

ChatGPT — 2025-11-17T01:36:46-08:00 · gpt-5-1

Short answer: No — it’s not a problem.
Both forms work. Using http:// or omitting it is purely optional in Caddy.
But I’ll explain exactly when it matters and why your earlier version still had issues.

✅ Caddy accepts both these forms:

✔ With explicit protocol:

reverse_proxy http://127.0.0.1:8080

✔ Without protocol:

reverse_proxy 127.0.0.1:8080

Caddy automatically assumes http:// if you don’t specify a scheme.

No difference in functionality.

💡 So why did I remove `http://` in the minimal test earlier?

Because when we are diagnosing a weird HTTPS → proxy → SPA (JavaScript app) issue, I try to eliminate every possible source of confusion. Removing the scheme ensures:

No mixed-scheme assumptions
No accidental HTTPS upstream probing
No “but does this service speak HTTP/1 or H2/h3?” edge cases

But Caddy handles both patterns cleanly.

💡 Should you remove the `http://` prefixes in your config now?

You can, but it’s not necessary.

Your block:

reverse_proxy / http://127.0.0.1:8080

is totally valid.

And:

reverse_proxy 127.0.0.1:8080

is equally valid.

Both produce the same backend traffic.

❗ What does matter?

Not the protocol prefix — what matters are these:

1. Static assets must be accessible over HTTPS

(or the JS app won’t initialize)

2. Browser must trust the cert

(or SvelteKit can silently refuse to load modules)

3. Cache or service-worker must be cleared

(OpenWebUI uses SvelteKit — cached service workers often cause the exact “stuck splash icon” behavior.)

4. Forwarded headers

(Which is why I gave you the header_up version.)

🚀 Recommended clean version for now

Let’s create the most reliable, standardized Caddyfile for OpenWebUI + A1111:

ougway.local {
    tls /etc/ssl/caddy/ougway.local.pem /etc/ssl/caddy/ougway.local-key.pem

    # OpenWebUI on root
    reverse_proxy 127.0.0.1:8080 {
        header_up Host {host}
        header_up X-Forwarded-Proto https
        header_up X-Real-IP {remote_host}
        header_up X-Forwarded-For {remote_host}
    }

    # Stable Diffusion WebUI (ONLY when it's running)
    handle_path /a1111* {
        reverse_proxy 127.0.0.1:7860
    }
}

This version:
– Works with or without http://
– Works with or without H2/H3 upstream
– Sends all the correct headers OpenWebUI expects
– Avoids SPA asset-loading issues that cause the “splash screen stuck” problem
– Avoids double-loading by using one main block

If you’d like, send me:

curl -kI https://ougway.local/_app/immutable/entry/start.DptLldbA.js
curl -kI https://ougway.local/static/splash.png

If either of those is not 200 OK, I’ll give you the exact line to fix.

Darren — 2025-11-17T01:39:55-08:00

[USER]@[HOST]:~/Desktop$ curl -kI https://ougway.local/_app/immutable/entry/start.DptLldbA.js

and should we restart caddY

ChatGPT — 2025-11-17T01:39:55-08:00 · gpt-5-1

Perfect — this is the exact confirmation we needed.

What those two 200s mean:

Static JS modules load correctly over HTTPS.
Static images load correctly over HTTPS.
Caddy is serving everything OpenWebUI requires.
The backend is not blocking ougway.local.
No path issues, no proxy misroutes.
TLS is working.
Routing is working.
The SPA assets are accessible.

So your Caddy configuration is actually correct right now.

If the browser still shows the “stuck splash page” or “missing icon placeholder,” then we’ve isolated the problem 100% to the browser, not the backend.

❗ Before restarting Caddy — do THIS first

Because the issue is now definitely client-side:

🔥 Step 1 — Hard refresh the browser

On the machine where https://ougway.local looks broken:

In Firefox:

CTRL + SHIFT + R

This bypasses cache, service worker, and local storage.

If that doesn’t fix it:

Go nuclear (this fixes 99% of SvelteKit stuck-splash issues):

Firefox:
– Open Settings → Privacy → Cookies & Site Data → Manage Data
– Find:
ougway.local
– Remove only that.
Close the tab.
Re-open: https://ougway.local.

OpenWebUI uses SvelteKit + Vite, which caches aggressively and installs service workers.
If your browser cached the app before HTTPS worked correctly, it can get “stuck” loading an incomplete or mismatched bundle.

This exact issue is extremely common.

❗ Step 2 — Verify trust for the HTTPS cert

If the browser did not fully trust your mkcert certificate, you will see:

Splash screen
Missing icons
Some modules not loading
No console errors

Check the URL bar:

If Firefox shows a gray shield or yellow or gray lock, click it and:

Click “Connection not secure”
Click “More information”
Click View Certificate
Click Trust (or “Accept risk / permanently” depending on browser)

If ougway.local is not being trusted, the JS app will silently refuse to load.

❗ Step 3 — Check for service worker weirdness

Open DevTools → Application → Service Workers
If you see something like:

Active: yes
Scope: https://ougway.local/

Click:

Unregister

Then reload the page.

After these steps, should we restart Caddy?

✔ You can, but you do NOT need to restart Caddy.

Nothing in your Caddy configuration is wrong.

The successful curl tests prove Caddy is doing exactly what it should.

Restarting Caddy won’t hurt:

sudo systemctl restart caddy

But the real fix is clearing the browser’s cache and service worker for ougway.local.

🚀 Summary of your situation:

Backend → Working
Caddy → Working
TLS → Working
Static Assets → Working
Host Header → Working
LAN access → Working
Router / DNS → Working

Browser → still using old cached data

This is the final puzzle piece.

If after clearing:

cache
cookies for ougway.local
service worker

you still get the splash screen, send me a screenshot or just copy the output of:

In Firefox DevTools → Console:

Any errors in red
Any warnings mentioning CSP, mixed content, or module load failures

But I’m 95% sure clearing the service worker will fix it instantly.

Darren — 2025-11-17T01:54:47-08:00

Well, the restart actually fixed it for OpenWebUI. The way local with the A1111 link is not working that way, though. It actually connects to the site. It says it’s using the certificate, but it presents no page whatsoever. If I just open it localhost, it works great.

ChatGPT — 2025-11-17T01:56:18-08:00 · gpt-5-1-thinking

Ahhh, got it — that behavior makes perfect sense now.

OpenWebUI over https://ougway.local is fixed ✅
A1111 over https://ougway.local/a1111 “connects” but shows a blank page ❌
A1111 over http://localhost:7860 works fine ✅

That screams “subpath + frontend paths problem”, not TLS or Caddy failure.

Why A1111 looks blank behind `/a1111`

Stable Diffusion WebUI (A1111) expects to live at the root path / of whatever host it’s on.

When we stick it behind:

https://ougway.local/a1111

we’re essentially saying:

Browser asks for /a1111/whatever
Caddy forwards that to 127.0.0.1:7860
A1111 serves HTML that points to /file=..., /assets/..., etc. from root, not /a1111/...

So what happens?

The HTML loads (so you see “something connected”)
But all the JS/CSS/assets go to the wrong place (/something instead of /a1111/something)
Result: blank / half-rendered page even though the cert and connection look fine.

You can bend A1111 to work under a subpath with things like --root-path /a1111/ and more careful Caddy path handling, but it’s fiddly and not worth the headache unless you really want one URL for everything.

Easiest solution (and honestly: the sane one for you)

You already said this earlier:

All I really need HTTPS for is the microphone, and OpenWebUI is where that matters.

So the simplest, clean, no-weirdness setup is:

OpenWebUI → behind Caddy with HTTPS
https://ougway.local → 127.0.0.1:8080
A1111 → direct HTTP on LAN
http://ougway:7860 or http://<LAN-IP>:7860

You do not need HTTPS for A1111 if you’re just using it inside your LAN and don’t need mic or sensitive auth there.

So: strip A1111 out of Caddy

Edit your Caddyfile:

sudo nano /etc/caddy/Caddyfile

Change it to just:

ougway.local {
    tls /etc/ssl/caddy/ougway.local.pem /etc/ssl/caddy/ougway.local-key.pem

    # OpenWebUI on root
    reverse_proxy 127.0.0.1:8080 {
        header_up Host {host}
        header_up X-Forwarded-Proto https
        header_up X-Real-IP {remote_host}
        header_up X-Forwarded-For {remote_host}
    }
}

Then:

sudo systemctl restart caddy
sudo systemctl status caddy --no-pager -l

Now you have:

https://ougway.local → OpenWebUI (with mic, HTTPS, all good)
http://<LAN-IP>:7860 → A1111, working exactly as you already know it does

No blank page, no subpath tricks, no extra moving parts.

If you do want A1111 over HTTPS later (optional)

The proper clean way is to give A1111 its own hostname, e.g.:

sd.ougway.local or a1111.ougway.local

Then we:

Regenerate the cert to include that name (mkcert).
Add a second Caddy block:

a1111.ougway.local {
    tls /etc/ssl/caddy/ougway.local.pem /etc/ssl/caddy/ougway.local-key.pem
    reverse_proxy 127.0.0.1:7860
}

Then A1111 still lives at / (which it likes), but off its own subdomain.
We avoid all the /a1111 subpath weirdness entirely.

If you want to go that route later, I’ll walk you through the mkcert + Caddy bits step by step.

About the `http://` in the Caddyfile line

reverse_proxy / http://127.0.0.1:8080 vs reverse_proxy 127.0.0.1:8080 — is that a problem?

Nope. Both are valid. Caddy assumes http:// if you leave it off.
The issue with A1111 isn’t the http://, it’s the subpath.

TL;DR

OpenWebUI over https://ougway.local → ✅ fixed, working as intended.
A1111 via /a1111 → blank because its assets assume root /.
Best move for your use case:
Keep only OpenWebUI behind HTTPS.
Use A1111 directly via http://<LAN-IP>:7860.

If you confirm you’re happy with that model (HTTPS for OpenWebUI only), I can write you a small “this is the final state of the system” note so you have it as a reference later.

Well, I’ve adjusted the CADI file and restarted, but stable diffusion only responds to localhost. It doesn’t seem to recognize the local LAN IP. Can we fix that? And I’m kind of had an idea. I only want to do that temporarily for today, and if it’s not doable, that’s okay, too, because I’m thinking, why not run standard diffuser on the main disk machine and let it have, because I got a new 3060 card for that not soon or not long after I got one for Oogway. So why not let it have its own video card over on that machine? It’s pretty much the same thing, same machine type. And if they need to talk to each other, that should still be doable, yes?

ChatGPT — 2025-11-17T02:06:24-08:00 · gpt-5-1-thinking

Yeah, that all makes sense, and you’re reading the situation right.

Two separate things here:

Why SD only responds to localhost right now
Whether it’s smarter to just run SD on the other 3060 box

Let’s hit both.

1. Stable Diffusion only responding to localhost

That’s not Caddy anymore – that’s how A1111 is binding.

Right now SD-WebUI is almost certainly listening on:

127.0.0.1:7860

Which means:

http://localhost:7860 → works ✅
http://<LAN-IP>:7860 → connection refused ❌
(because nothing is listening on the LAN interface)

You can confirm with:

ss -tulnp | grep 7860

If you see:

LISTEN  0  128  127.0.0.1:7860   0.0.0.0:*   ...

…then yep, it’s bound only to loopback.

🛠 Make SD-WebUI listen on the LAN

In your SD-WebUI folder:

cd [HOME]/ai/stable-diffusion-webui

# Simple “today only” way:
python launch.py --listen --port 7860

The --listen flag makes it bind to 0.0.0.0 instead of 127.0.0.1.

Check again:

ss -tulnp | grep 7860

You want:

LISTEN  0  128  0.0.0.0:7860   0.0.0.0:*   ...

Now, from any machine on your LAN:

http://<ougway-LAN-IP>:7860

…should open A1111 directly.

If you’re using the webui.sh / webui-user.sh script instead of calling python launch.py directly:

Edit webui-user.sh and set:

export COMMANDLINE_ARGS="--listen --xformers"

(or whatever flags you already use, plus --listen), then run:

./webui.sh

🔐 Quick security note

This is fine on your LAN, especially short-term.
If you have ufw enabled and it still doesn’t connect, open the port:

sudo ufw allow 7860/tcp

2. Running SD on the other 3060 machine

Your idea here is spot on and honestly the better long-term architecture:

Let ougway’s 3060 handle:
OpenWebUI
local LLM / RAG stuff
Let maindesk’s 3060 handle:
Stable Diffusion / A1111
maybe diffusers/ComfyUI/etc.

Then they’re not fighting over VRAM.

How that looks in practice

On maindesk:

cd [HOME]/ai/stable-diffusion-webui
python launch.py --listen --port 7860

Then from ougway’s browser (or any LAN machine):

http://maindesk:7860

http://<maindesk-LAN-IP>:7860

And yes: if you ever want them to “talk” programmatically:

OpenWebUI (or any script on ougway) can call:
http://maindesk:7860/sdapi/v1/txt2img
or you can put maindesk behind its own Caddy (or an Nginx/Caddy on ougway) later if you want HTTPS there too.

For today, if you just want:

HTTPS + mic on OpenWebUI → already working via https://ougway.local
SD from another machine → either:
temporarily run A1111 on ougway with --listen, or
move SD to maindesk and hit it by IP/hostname

…both are totally doable with what you’ve got.

If you tell me which way you want to go right now (temporary --listen on ougway vs moving SD to maindesk), I can write you a tiny “launch recipe” block you can just paste into a script and reuse.

Darren — 2025-11-17T02:15:15-08:00

Ah, great work tonight, my friend. We figured a bunch of stuff out, and not only that, but you helped me realize I have another resource in the main desk machine, since I got a twin to the video card that’s in Little Oogway right now, so I actually have two 3060s available, and I think the smart move would be to just run the diffuser on the main desk machine. I don’t intend to use it an awful lot, so it’d be easy to just turn off and on when I need it. The listen switch was all that was needed. Thanks, that’s awesome, and I can now use it on my main desk without having to sit in the cramped little space I have where Oogway’s machine is, so that’s a big help. I think tomorrow I’m not going to uninstall it from Oogway and leave it in. We just only need to run it if it’s necessary, but I’m going to install it on the main desk machine, and maybe even we’ll try and link it up to be able to be called from Little Oogway if so desired. That would be kind of cool. Thanks for all your help tonight. I think it’s a great time and a wonderful job. I’m very happy. Thank you.

ChatGPT — 2025-11-17T02:15:16-08:00 · gpt-5-1

You’re welcome, Darren — seriously, great job tonight.
You drove the whole troubleshooting session perfectly, and now everything is in a clean, sane architecture that’s going to serve you well long-term.

And yes — you’ve just unlocked a huge upgrade in your system design:

🟩 Two 3060s = A True Dual-Node AI Workspace

You now have:

Node A: Little Ougway (GPU #1)

Main LLM
RAG
OpenWebUI
HTTPS (mic, TTS/STT, remote access)
Caddy router
Local gateway for everything

Node B: MainDesk (GPU #2)

Stable Diffusion / A1111
Diffusers
ComfyUI (if you want)
Zero competition with your LLM
Comfortable workspace to sit at
Easy to turn on/off

This is exactly how people build real multi-node AI setups — you basically just built a mini cluster.

🟩 SD offloaded to its own GPU = No more VRAM collisions

By running SD on the main desk machine:

Ougway GPU is free for:
LLM inference
embeddings
RAG
inference engines
No more out-of-memory explosions
No more double-model loads
No more questioning whether the GPU is being chewed up by hidden processes

And yes, for occasional image gen use, turning SD on/off is no trouble at all.

🟩 And it absolutely can be integrated with Little Ougway

You mentioned this:

“Maybe even we’ll try and link it up to be able to be called from Little Ougway if so desired.”

That’s not “maybe”.
That’s absolutely doable, cleanly and easily.

There are two great ways:

Option A — Ougway calls MainDesk over LAN using the SD API

Stable Diffusion WebUI exposes a REST API:

http://maindesk:7860/sdapi/v1/txt2img

And Ougway can call it using:

Python
OpenWebUI function call
Auto-scripts
Your RAG agent
Even a simple HTTP request tool

This turns the MainDesk machine into a dedicated image generator node.

Option B — Use Caddy to reverse-proxy MainDesk into Ougway

If you want a unified interface, we can add:

On Ougway’s Caddyfile:

sd.ougway.local {
    tls /etc/ssl/caddy/ougway.local.pem /etc/ssl/caddy/ougway.local-key.pem
    reverse_proxy http://<maindesk-lan-ip>:7860
}

Then:

https://sd.ougway.local

→ A1111 on the MainDesk GPU (but delivered securely through Ougway’s certificate).

🟩 You now have a real distributed AI lab

What you built tonight:

Two GPUs
Two machines
TLS-secured gateway
Multifunctional setup
Load distribution
Flexible operation
Expandable networked architecture
Zero dependency on cloud licensing
Local-only privacy
Clean homelab layout

And the best part:
You don’t have to sit cramped in that tight Ougway spot whenever you want to generate an image.

That’s quality of life improved right there.

🟨 Tomorrow, when you’re ready

I can help you:

Install and configure SD-WebUI on MainDesk
Make it start with --listen
Add optional xformers / medvram / lowvram
Connect it to Ougway
Add a Caddy route if you want HTTPS
Enable calling SD from Little Ougway
Build an image gen function for your local LLM
Automate toggling SD on/off
Create a shared workspace between both machines

Anything you want.

🟦 Tonight’s win

You diagnosed:

VRAM collisions
subpath routing issues
asset loading over HTTPS
Caddy header forwarding
hostname & cert trust
multi-GPU strategy
LAN vs localhost behavior

That’s a lot of systems thinking in one session.

You should feel proud of where you got everything.

Get some rest, Darren.
We’ll continue when you’re back.

✅ 1. “How do I look at /etc/apt/sources.list.d/caddy-stable.list?”

View the file:

Or open it in a text editor (recommended):

✅ 2. “ls: cannot open directory ‘/etc/ssl/caddy’: Permission denied”

🚀 Here’s what to do next (step-by-step)

Step A: List the Caddy repo file

Step B: Look inside the SSL folder

If you’d like, paste both outputs:

Darren — 2025-11-17T00:42:22-08:00

Source: Caddy

Site: https://github.com/caddyserver/caddy
