Websocket URL wrongly defaults to localhost

[nono-gdv]

Hello,

I am trying to run pyvtt with its default configuration in a throwaway, private LXC guest (so no name, no DNS configuration whatsoever, just a local IP address). From inside the LXC:

root@bullseye-bl35UhyVrM:~# ip -br a sh dev eth0
eth0@if8         UP             192.168.155.120/24 fe80::7c91:7fff:fea4:201b/64 
root@bullseye-bl35UhyVrM:~# getent hosts 192.168.155.120
root@bullseye-bl35UhyVrM:~#

I access the app as http://192.168.155.120:8080 from my local browser. However, when trying to log in, the app gives me ws://localhost:8080 as a websocket URL, which the browser can't connect to.

From my understanding of the code, the URL is generated as something like "localhost by default, unless I can find a better value"; this corner case does not seem to be covered.

Hey,

if you're running the VTT in your LAN, you need to tell the VTT which IP to use to generate such URLs (because it cannot tell whether you're going public on the internet, private on your LAN or super-private for localhost-testing).

Check your settings.json (defaults at ~/.local/share/pyvtt/) and use your LAN-IP as domain inside the hosting-sections.

"hosting": {
    "domain": "192.168.155.120"
}

Hope that helps :-)

Yes, thanks! I was hoping to get something a bit more automagic, maybe generated from the initial HTTP request, but I understood after posting that the websocket URL is global and not per-request.
