CONFERENCE FAILED: conference.videobridgeNotAvailable

hey guys,

since short time, I am having this issue:

2020-11-24T09:53:47.527Z [conference.js] <te._onConferenceFailed>: CONFERENCE FAILED: conference.videobridgeNotAvailable

in my jvb log, i see:

JitsiMeetConferenceImpl.log() Can not invite participant -- no bridge available.

but I see that I have videobridge2 is running:

/var/log/jitsi# service jitsi-videobridge status
Unit jitsi-videobridge.service could not be found.

is this may be the issue?

That is from jicofo log, you need to check jvb log and see why it disconnected from the xmpp server
