Conference - App Crashes for everyone after few minutes of live streaming android SDK (HIGH PRIORITY)

[Sachin Gupta]

While  we are doing a conferencing app is crashing for everyone frequently, we debug the issue and found for some user Java.io.IOException: Connection reset by peer in server logs due to which websocket  connection has been closed for everyone and app is crashing. Attached is the log snippet from server logs :
