Hi @arfa.ahmed ,

This is expected behavior. When a host leaves the session, it will automatically end unless someone is assigned co-host.

Thanks,

Hey @arfa.ahmed

Thanks for your feedback.

Has the host already left the session? Or was it manually triggered to join the session again?

Otherwise, if the session is reconnected, the sequence of event payload is as follows:

connection-change:{"state":"Connected"}
connection-change: {"state":"Reconnecting","reason":"failover"}
connection-change: {"state":"Connected"}

Thanks

@vic.yang yes, mostly receiving this pattern but sometimes receiving state “Closed” also like this:

connection-change:{"state":"Connected"}
connection-change:{"state":"Closed"}
connection-change:{"state":"Connected"}
connection-change: {"state":"Reconnecting","reason":"failover"}
connection-change: {"state":"Connected"}

and this also not leaving the user

Hey @arfa.ahmed

It’s quite unusual.

Typically, the connection-change:{"state":"Closed"} event occurs when someone leaves the session or when the session is ended.

Could you please report the logs to us when the issue occurs again? It would be really helpful for us to investigate further.

Thanks
Vic
