[beta-alpha001]

What happened and what did you expect to happen?

Sometimes meeting get stuck in connecting state forever, with warnings like
Your connection is poor
no transition found from Disconnecting with Update
peer connection negotiation is needed
will retry due to status code ICEGatheringTimeoutWorkaround and error: serial group task AudioVideoStart/6ae8a1fb-83b8-4523-900b-8e7484d60706/a40909b6-4556-bc90-81dd-1c8b4512edb3 was canceled due to subtask AudioVideoStart/6ae8a1fb-83b8-4523-900b-8e7484d60706/a40909b6-4556-bc90-81dd-1c8b4512edb3/Timeout15000ms error: serial group task AudioVideoStart/6ae8a1fb-83b8-4523-900b-8e7484d60706/a40909b6-4556-bc90-81dd-1c8b4512edb3/Timeout15000ms/Peer was canceled due to subtask AudioVideoStart/6ae8a1fb-83b8-4523-900b-8e7484d60706/a40909b6-4556-bc90-81dd-1c8b4512edb3/Timeout15000ms/Peer/SubscribeAndReceiveSubscribeAckTask (once) error: canceling FinishGatheringICECandidatesTask due to the meeting status code: 16

Meeting keeps on retrying to connect, however it should throw some error event like meetingStartFailed after some threshold duration, so that we know user is facing issues in connecting

The default threshold for reconnect is 15s as mentioned in our FAQs. You should also receive audioVideoDidStop event.

Hi @ltrung,
I'm using amazon-chime-sdk-component-library-react, which adds audioVideoDidStop observer, which publishes MeetingStatus.Failed on ICEGatheringTimeoutWorkaround. I was able to reproduce the issue and meeting status did not change throughout the connecting state. I'll add the logs. I'll also report this on amazon-chime-sdk-component-library-react
Also I see reconnectTimeoutMs is 2mins, so after 2mins which event will we receive ?

Hi @beta-alpha001,

Tested on React meeting demo, if we have disconnected for over 2 mins, we will receive following logs/events:

• transitioning from Connected to Disconnecting with Fail
• transitioning from Disconnecting to NotConnected with FinishDisconnecting
• AudioVideoClean
• removing meeting observer
• Stopping DefaultStatsCollector
• removing a ping-pong observer
• removing meeting observer
• ReleaseMediaStreamsTask
• Non-Terminal failure occured: 19

Code 19 is for TaskFailed, a task failed for an unknown reason.
