After upgrade to jitsi-meet 2.0.5390-3 I has audio/video troubles, fixed by adding
org.ice4j.ice.harvest.NAT_HARVESTER_LOCAL_ADDRESS=<Local.IP.Address>
org.ice4j.ice.harvest.NAT_HARVESTER_PUBLIC_ADDRESS=<Public.IP.Address>
in /etc/jitsi/videobridge/sip-communicator.properties as per the wiki.
By the way, it works now, but meeting clock is always 00:00.
