Description

The websocket connection is getting disconnected after 5mins or so of idle time.

The connection is getting disconnected by the AWS Load Balancer. Its considering the connection as closed as the server is not sending out any PONG msg in response to the PING msg from the client. 

The TCP Keep-alive packets do not prevent idle timeouts in ALB. So since the server is not sending any PONG msg the ALB is treating the connection as inactive and terminates when the timeout period is elapsed.
