"No Listener Configured" in AlwaysOn dashboard replica details when DNN listener is used
When a Distributed Network Name (DNN) Listener is used the Listener is not displayed in the Always On Availability panels.
A message "No listeners are configured" is displayed in the Replica Details popup.
There are is no listener IP status information in SQL Server DMVs for DNN listeners, on the DNS name and port.
Enhancement Request ID FGSS-I-149 has been logged to display a DNS name and in the IP status field show "DNN listener" instead of the IP status in the popup. This will be reviewed by Product Management for consideration in a future release of the SQL Server cartridge.
DNN listeners are available in SQL Server starting with either SQL Server 2019 CU8 and later, SQL Server 2017 CU25 and later, or SQL Server 2016 SP3 and later on Windows Server 2016 and later.
