Sophos Firewall - Users automatically kicked out of the session

Hello to all,

we have problems to get our Jitsi Server running. As soon as two people are in a room, they are automatically kicked out of the session after about 10 to 15 seconds.

The Jitsi server is installed on an Ubuntu 20 and hangs behind a Sophos firewall and has been released to the outside world via Sophos’s web server protection. Intrusion Detection - UDP flood protection is disabled.

We cannot explain what causes the automatic disconnection of users in sessions.
We would appreciate any help.

Thanks Marc

Check js console logs, most probably the error is ICE failed, this means firewall, port forwarding not working for udp 10000 or the bridge does not announce its public address, this is covered in advanced section of https://jitsi.org/qi.
