Participant pair can not be selected

[arnasledev]

Describe the bug
While trying to establish a connection between two participants, one failed—and it always fails when this client tries to connect to a video session when other participants are already connected.

If this client connects first, then everything seems to be fine all the time. I assume the bug occurs only when other clients are connected.

Server

• Version: v1.5.2
• Environment: Self-managed Kubernetes v1.28.4
• 2x Livekit-server instances with Redis Sentinel

Client

• SDK: js/ts
• Version: 2.0.3

To Reproduce
Steps to reproduce the behavior:

1. client with chrome joins the meeting
2. 2nd client tries to join with firefox
3. 1st client sees that 2nd client came in to the meeting but no tracks are published, while 2nd client is still trying to connect
4. 2nd client gets error and is disconnected from the video session

Expected behavior
Clients should be connected all the time

Yes and no simultaneously - we tried the same and got the same result; I saw participant B as connected, but without the tracks, and after some time (like the 30s), he came alive. Adding logs from the Participant B's perspective
