I have a Jitsi Meet - now version 2.0.4 - on Debian 10.
At first everyone was happy with it, now a frequently get complaints about people dropping out of meetings and bad audio and video quality.
I suspect this could be because at first everybody was at home but lately people come back to the office where there are behind a nat firewall.
The EM I’m seeing in /var/log/jitsi/jvb.log:

So what I’m seeing is the domintspeakerchanged message and the timeout for pair message.
The firewall on the Jitsi server ( Shorewall ) is set to open ports udp 10000 to 30000.
Can anyone help on this issue?
