Jitsi with Plesk shows grey screen

Continuing the discussion from Noob question: URL shows PLESK Admin Interface instead of jitsi.org:


I have installed Jitsi with Plesk.
The connection with the subdomain also seems to have worked. However, when I call up the page, a grey screen is displayed.

Does anyone have an idea what could be wrong? Thank you very much.

This log shows XMPP connection error, you can check the connection details in /etc/jitsi/ and /etc/prosody/, also check if you have the prosody accounts in /var/lib/prosody/ created and whether their passwords are correct. I’m not sure whether this log is from jicofo.log or jvb.log, but check both prosody users.

I guess the error is from Jicofo, that’s why you see a grey screen. Otherwise if JVB is malfunctioning, you will see initially your video and when a second user tries to join, you will see a an error message and timeout to retry. So in your case check jicofo settings, for some reason jicofo can’t authenticate to prosody server.

If you see a grey screen on the whole page and you can’t load even the initial own video - then you most probably have a syntax error in the configuration js files (config.js, etc.). For example a misplaced end-line comma.
