Hi, this is the situation /question:
Jitsi works well - but there is one participant behind a firewall. With this participant the video (audio) is missing.
Coturn was set exactly how it is described here: Setting up TURN · Jitsi Meet Handbook (implemented turn server on 443).
The participant behind the firewall still does not have video (with other participants still well)
https://meet.jit.si/ does pass the firewall with video - so: generally it works.
What could be the reason why my system does not pass the firewall?
I am not sure if coturn really works well - but closing port 10000/udp in the router does not have any effect on participants without firewall; they still get the video - so I guess coturn works, right?
Thanks for any advice
