Google Cloud IOT Core Fails re negotiate JWT

Hi

When the JWT token expires the connection is dropped by Google. The connection is not established. Steps to replicate - reduce the JWT EXP time to 10 mins. The Token will expire and communication with IOT core will stop.

Is there a connection watchdog to restart the connection of poll fails to get a response?

Start by reproducing the connection failure with the JWT expiration reduced to 10 minutes, then inspect the example's connection and token-renewal handling. Done means communication with Google Cloud IoT Core resumes after the JWT expires, including recovery when polling or reconnecting fails.
