No audio/video

Hi Everyone,

I've just installed Jitsi-meet on a new Debian server. When I start a new conference the chat works well and I can see participants' names but I can't see or hear them (webcam and audio not working). I get this error "OperationFailedException: ICE failed" in /var/log/jitsi/jvb.log :
