[BUG] Manual Resolution in HTTPS when behind ngrok doesn't work

[luiso1979]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

Using a slightly modified ubuntunoble, when I specify -e SELKIES_IS_MANUAL_RESOLUTION_MODE=true -e SELKIES_MANUAL_WIDTH=1920 -e SELKIES_MANUAL_HEIGHT=1080 while running the container behind an ngrok and point the browser to https://ID.ngrok.app all I can see i just a little fragment of the desktop.

Expected Behavior

I expect to see the scaled desktop centered in the browser, like when I open the exact same container and access it via the http://localhost:3000 or https://localhost:3001 .

Steps To Reproduce

1. run a container derived from this one, like for instance a lscr.io/linuxserver/webtop:ubuntu-xfce using the envs specified
2. then use the ngrok command: ngrok http 3000 or ngrok http https://localhost:3001
3. the open the ngrok URL

Environment

- OS: MacOS M2 (but tested also in AWS Linux)
- How docker service was installed: Docker desktop (yum in AWS Linux)

land on that url in a private window or clear your cache first you may have conflicting setting hard coded into your client from previous versions.

Thanks @thelamer, but using an Incognito instance of chrome the result is the same. It seems related with webRTC behind a proxy (ngrok) but I'm not so sure.

[luiso1979]

The exact same problem happens when I set the env SUBFOLDER. And in this case it happens from everywhere, localhost, ngrok, http and https.

[luiso1979]

I took a look at the DOM in both cases, and behind ngrok (or with the SUBFOLDER set) I get this canvas:

<canvas id="videoCanvas" width="2048" height="1536" style="width: 1024px; height: 768px; position: absolute; top: -384px; left: -512px; object-fit: fill; display: block; image-rendering: auto;"></canvas>

Whereas in the other case (plain localhost:3000 or 3001):

<canvas id="videoCanvas" width="1920" height="1080" style="position: absolute; width: 321.778px; height: 181px; top: 0px; left: 595.111px; object-fit: contain; display: block; image-rendering: auto;"></canvas>

See that in the second case it set the canvas with the correct dimensions and resizing, whereas in the first case it completely ignored my manual dimensions and set a broken resizing.

Maybe I'm missing something in the configuration, since I don't see nobody complaining about this, and I doubt I'm the first 😄

Thanks in advance for the support

Ok I think I know what is going on (not why 😸 ). The localStorage properties:

HOSTNAME/_manual_height
HOSTNAME/_manual_width

weren't set every time it didn't work, and viceversa. And by manually setting them it did start working as expected.

I don't know why it doesn't get set in the first place though.

[luiso1979]

I must seem like a lunatic talking to myself, but I found a workaround. I added to the file /root/defaults/startwm.sh just before the line that starts the xcfe session (or whatever happens at the end of yours):

if [[ -n "$SELKIES_MANUAL_WIDTH" && -n "$SELKIES_MANUAL_HEIGHT" ]]; then
    sudo sed -i "s|<head>|<head><script>const prefix = window.location.href.split('#')[0].replace(/[^a-zA-Z0-9.-_]/g, '_');localStorage.setItem(\`\${prefix}_manual_width\`, \"$SELKIES_MANUAL_WIDTH\");localStorage.setItem(\`\${prefix}_manual_height\`, \"$SELKIES_MANUAL_HEIGHT\");<\/script>|" /usr/share/selkies/web/index.html
fi

This conditions forces the localStorage props HOSTNAME/_manual_width and HOSTNAME/_manual_height set to the respective env vars (if specified)

But I think of this as a hacky workaround.
