I have two ADFS 3.0 servers and two ADFSproxy servers(DMZ). All located in Azure. The machines all or load balanced.
Now i try to add a windows 2016 server (ADFS 4.0) on a different VNET but peer with the old VNET.
When i try to add the ADFS 4.0 (windows 2016 machine) I get this error.
Unable to retrieve configuration from the primary server. The specified DNS name of the primary federation server could not be resolved. Verify that the DNS name is correct, and that the AD FS service is running on the primary federation server and try again.
