Jitsi only listening on udp6 port 10000 and not udp4


I am trying to understand what is preventing Jitsi from listening on udp4/10000.

netstat -an shows udp6 listening:
udp6 0 0 :::*

Operating system is Ubuntu. Does anyone know what would prevent this from listening on udp4 and how to resolve?


EDIT: disabling IPV6 in Ubuntu does now show it listening properly but now Jitsi is broken.
udp 0 0*
EDIT2: changing org.jitsi.videobridge.rest.jetty.host from :: to the IP address fixed.

You can add the ‘-p’ flag to netstat (you’ll need sudo) to see which process has bound the port.
