The latest version of Jitsi Meet DNS polls multiple servers

I have installed the latest version of Jitsi Meet and used DNS round-robin to connect to multiple servers. However, when multiple devices enter the same room name, they cannot enter the same room and instead enter separate rooms. How can I solve this problem? What configurations do I need to make? Any help is appreciated, thank you!

Every client attaches room=… parameter to the request that are made. You need to stick sessions based on that. Participants to the same room need to end up on the same shard. You can do that using haproxy. Search the forum there several posts about it.
