We installed a fresh jitsi stable 8218 with docker in an firewalled environment (flows from clients to the jitsi server are opened (8443/tcp + 10000/udp)) and no Internet access.
Unfortunately we’re unable to share screen (a black screen is presented to other parties).
I noticed p2p is used when sharing content, if that’s the case then it could explain our issue as flows between clients are filtered, is there a way to force a direct connection to the server only ?
I also noticed an error message sent every minute in the jvb container :
java.lang.Exception: Address discovery through STUN failed
I guess the reason is that the server is unable to reach the STUN servers from google, our server have no public IP, could it be a problem?
Is there a way to disable STUN resolution? I found some article but they are quite old and none seems to fit the current configuration files.
