After upgrading from “Ubuntu 18.04” with “jitsi-videobridge2/stable 2.1-416-g2f43d1b4-1”, to “Ubuntu 20.04” with “jitsi-videobridge2/stable,now 2.1-634-gff8609ad-1”, UDP port for Harvester doesn´t raise:
sip-communication.properties has next parameters:
org.ice4j.ipv6.DISABLED=true
org.ice4j.ice.harvest.NAT_HARVESTER_LOCAL_ADDRESS=10.0.12.65
org.ice4j.ice.harvest.NAT_HARVESTER_PUBLIC_ADDRESS=

org.jitsi.videobridge.STATISTICS_TRANSPORT=muc
org.jitsi.videobridge.octo.BIND_ADDRESS=10.0.12.65
org.jitsi.videobridge.octo.BIND_PORT=4096
