ConnectException: DataChannel "RELIABLE" not established during metrics collection

[abbasnaqdi]

I'm encountering a RoomException$ConnectException in my Android app using LiveKit SDK 2.24.0 and Server 1.9.1.

The error specifically triggers during metrics collection (RTCMetricsManager.kt:104). It seems the SDK attempts to send subscriber metrics over the RELIABLE data channel before it's fully established or after it has been closed.

Log:

I’ve searched through the documentation and existing issues but couldn't find a solution or a similar report.

Questions
What is the root cause of this "channel not established" error during the metrics collection phase?
Is this a known race condition in version 2.24.0?
How can I ensure the RELIABLE channel is ready before the metrics manager attempts to use it?
