It works, many thanks @endel

Thanks for workaround. I think that the only way for now

Hi @endel , thanks for quick response.
If I understand correctly, dynamic proxy is a load balancer for colyseus instances. I organize my servers like below:

Client 1 (C1) has joined room L1
Client 2 (C2) has joined room L2

I want the two clients to join the same Game Room, for example G1. So I wonder if redis presence can solve this problem ?
Many thanks

Hi guys,
I'm using redis presence for my colyseus instances. The problem is when one instance is shutdown, its process id still remain in redis, so the presence db will get bigger over time. I'm afraid this will increase query time. Is there any solution to clear unused process ids in redis presence ?
Many thanks

Hi guys,
I'm using colyseus for my online games and want to scale up multiple servers. I have 2 instances running with redis presence. My client C1 joined room R1 on the first instance, then I want client C2 (connected to second instance) to join room R1 but it not worked. Any solution for this ? Is there anyway to make the match maker work across servers ?
