Can't establish a connection to server. Websocket error in docker implementation

I have a self hosted jitsi-server in Centos 7 with docker implementation. You can visit to the server at domain microteams.tech
The issue is that whenever I try to start a random room it redirects to rejoin without establishing a websocket connection.
What can be the reason for that?
P.S. You can reproduce the error by visiting microteams.tech
