Web-socket handshake issue, audio and video of participant black out while third participant join

Hello team,

I have set-up Jitsi server in my azure VM ubuntu 18.04. Facing Bridge Channel send: no opened channel and after third participant joined no audio and video for more than two participant. Followed “Self-Hosting Guide - Debian/Ubuntu server · Jitsi Meet Handbook” and also made changes mentioned here “jitsi-videobridge/web-sockets.md at master · jitsi/jitsi-videobridge · GitHub”.
