videobridge is not able to connect to Prosody, jibri does not work at all and breaks functionality to join rooms

[renepardon]

I've an easy setup with Jitsi Meet, Jibri Server and videobridge but a bunch of errors.

When all playbooks were executed successfully, on JVB I see:

I also came across jitsi/jitsi-meet#3639 and disabled bosh to listen on HTTPS.
If I enable "recording" there is an additional problem with Jibri and the included presence_identity module. See: jitsi/jitsi-meet#8284

Hi, Christoph. I'm not sure what could have happened, but the authentication configuration in the videobridge does not match the one in prosody. You should check it is OK (matching) in /etc/jitsi/videobridge/sip-communicator.properties and /var/lib/prosody/..../accounts/your_videobridge.dat.
