Redirect jitsi other port

Greetings friends I am using jitsi behind a firewall, I cannot use port 443 because it is using a web server, I have changed to use port 4443 I have changed in nginx and it works, I have the problem that the microphone and the camera appear disabled

I have searched the net but can’t find an answer to help me solve this problem, could someone please help me with this problem. I followed this guide https://github.com/jitsi/jitsi-videobridge/blob/master/doc/tcp.md but it didn’t work for me either

Thank you all
