Scenario: Windows Server 2012R2 & SQL Server 2014 SP2, no CUs FCI adding a non-default port and keeping the default port
I made the change on both nodes via SQL Configuration Manager, however, neither failover or complete resource restart allows a connection to be made on the new port. We have tested connection to the port with the application, telnet and PoSH (Test-NetConnection) to no avail. The SysInternals PortMon utility does not show SQL Server listening on the added port. I did confirm the port shows in the registry on both nodes.
Edit: A huge detail I should have listed but forgot to. When the service restarts, there is not indication that it is listening on the new port, just the default.
What did I miss or what else do I need to check?
Obviously, I cannot test any changes without some notice.
Thank you in advance!
