Hi I have an AppGateway with a public IP address that is load balancing IIS servers. When I try to setup a zone manager endpoint I get the validation message "No DNS name is configured" when selecting my App Gateway. I see the same message if I also select a public IP of the servers directly.
If I configure the endpoint as external with the same IP address everything works fine.
I configured the monitor URL in both the AppGateway and my backend servers.
When using the 'Azure Endpoints' endpoint type, the Public IP Address you add must have a DNS label on it.
If you are using an Application Gateway, it is not supported for the Azure Endpoints type, you should add it as an external endpoint.
The tutorial here - https://docs.microsoft.com/en-us/azure/traffic-manager/traffic-manager-load-balancing-azure - uses AzureEndpoint as endpoint type for configuring app gateways' public ip as endpoints. Which one to go with? I have not had luck with either of this approach.
I am facing the same issue, any suggestion?
