Is it possible to run jitsi on port 443?

I am using dockerized jitsi. When I change the value of JVB_PORT in the .env file to 443, I get the following error:

WebSocket connection to 'wss://XXXXX.tld/colibri-ws/172.19.0.5/94f10d64?pwd=7dc57ri... failed: ...

note that 172.19.0.5 is the jvb’s docker container IP and that I have set the correct value for the DOCKER_HOST_ADDRESS considering that when JVB_PORT’s value is changed to 10000 everything works fine. Is it at all possible to run jvb on port 443.

ps. I am running dockerized envoy on port 443/tcp.

Not familiar with docker, but port 443 is typically reserved for https requests. If you want to relay media over it, you’ll need to deploy a TURN server.
