Application team is receiving the following error message when applications try to connect through the Availablity Group Listener using readonly parameter:
"An exception has been raised that is likely due to a transient failure. If you are connecting to a SQL Azure database consider using SqlAzureExecutionStrategy."
Already using latest .net framework. Using the Extended events I can trace the read_only_route_complete event as well. However, they get this message when trying to open the read only database.
If I try to simulate the connection to ReadOnly replica from management studio, it is working successfully. But not from the application:
Note:
-verified firewall is disabled. (this is development environment)
-SQL Server 2012 SP2 is installed.
