You are the only one in the meeting

My fairly new install stopped working after the recent upgrade. Now each end can only see themselves and not others. How does one go about debugging this?

Hi @andro did you checked firewall ports and systemctl daemon-reload and service jitsi-videobridge2 restart

It’s not firewall. Disabling ufw - same problem. Service restarting makes no difference.

Is this error I just found related? in the prosody logs:

Error binding encrypted port for https: No certificate present in SSL/TLS configuration for https port 5281

Those prosody logs you can ignore.
Start from the Javascript console in the browser, do you see any errors? Then check jvb or jicofo logs for errors?

I have to same issue. I have this log in the JS Console:
