useMeetingStatus doesn't give updated status on ICEGatheringTimeoutWorkaround

[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

in such cases audioVideoDidStop event is received.
I'm using useMeetingStatus which doesn't give updated value of meeting status i.e. MeetingStatus.Failed in this case.

Hi @beta-alpha001,

Thanks for reporting this issue. The normal events that should be received after AudioVideoClean is ReleaseMediaStreamsTask and session stopped with code: X. However in this log, it retried since the status is ICEGatheringTimeoutWorkaround.

Not sure if the problem only happens in Chrome, if it is, then this could be an indication that the browser is in a bad state due to a VPN reconnect and the user should try quitting and relaunching the app. See: https://bugs.chromium.org/p/webrtc/issues/detail?id=9097

It would be great if there are steps to reproduce the problem.

Hi @jing-chen1, thank you for the response.

It would be great if there are steps to reproduce the problem.

User has Realme X50 Pro 5G on which this issue is reproducible every time they try to connect with chime in both chrome and firefox, however I'm not able to reproduce this on other devices. Relaunching application doesn't help.

Question:
Shouldn't we get audioVideoDidStop event when it retries due to status ICEGatheringTimeoutWorkaround ?
If yes, then can we mock ICEGatheringTimeoutWorkaround and check why useMeetingStatus doesn't update meeting status to MeetingStatus.Failed.

Hi @beta-alpha001 ,

The audioVideoDidStop will be triggered:

1. When the meeting has failed completely with a terminal failure else JS SDK will attempt re-connection.
2. In the app, meetingSession.audioVideo.stop() is called.
3. Else, the re-connection times-out configured using the reconnectTimeoutMs through MeetingSessionConfiguration in JS SDK and MeetingManagerConfig through Chime react component library.

Hence, if a meeting session runs into the ICEGathering failure, the SDK ran into a WebSocket close event not receiving issue, hence, the Amazon Chime SDK for JavaScript would keep on re-connecting until it connects successfully resulting into no audioVideoDidStop trigger. This was a bug and we have seen your issue like behavior in a more recent issue and may be related.

The issue was fixed in amazon-chime-sdk-js@2.27.0 and since there is no Chime component release done yet, the current version still depends on 2.26.0. Could you please confirm if updating the Chime component library version to latest, as well as the amazon-chime-sdk-js version to the latest solves your issue?
