I have to configure App Gtwy between Traffic Manager and Azure Web apps. I have a custom domain for my web app and uploaded certs (pfx and cer) in App gateway. Added App Gtwy endpoint in Traffic Manager Profile. Uploaded the pfx cert in Azure Web App. Added DNS entry from custom domain to Traffic Manager Public endpoint.
Now how to have end to end SSL configured in App Gateway?. While doing SSL binding in Web app, HostName is not getting validated as there is already a CNAME configured for my custom domain to Traffic Manager public endpoint.
Can someone please help me in understanding how the DNS configuration should look in this case?
