I am using the NotificationHandler along with the Ping/Pong approach to ensure the connection is up. Do I need to write special logic if a Ping is called and no Pong is responded within a certain amount of time to confirm that the connection is down? I always see the Pong notification following the Ping request but last night my service which had been running for weeks just stopped receiving notifications. I noticed in the logging that the Pong stopped coming in which made me think that the service was sending the Ping but not getting a Pong and as such I need to have some check to ensure the previous ping received a response.

Yes. The purpose of the ping/pong feature is to validate that the connection is still healthy. If you don't get a pong within a couple seconds, or you don't get a heartbeat every 30 seconds, the app should consider the connection down and take steps to recover.
