I am having an issue with SQL 2012 Availability Groups where it does not fail over when shutting down the service. When you shut down the service you will get an error:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.
It appears that the listener is still trying to listen off of the node that was just shutdown.
If I attempt to manually failover in SSMS, it fails over successfully.
I am not sure exactly what is the root cause of this issue since I was able to shutdown the service previously and it would failover. I thought the problem had been resolved.
I have tried to set the maximum failures in the specified period to 25 for every hour.
