AWS SSM server re-registration when connection is lost
We noticed that sometimes teams perform re-registrations when they have servers that are in connection lost state. This registers the server with a new instance ID again in the SSM console instead of using the previous registration. The previous instance ID will stay in the console in the connection lost state until it is manually cleaned up/deregistered.
When connectivity is restored shouldn't the agent restablish the link to the original registration? Is there a setting to enable this capability? This would help us to reduce the time we spend on remediating connection lost servers and duplicates as explained above.

The agent should reestablish the connection to the AWS SSM Endpoint.
