title: External domain in web app
body: <p>After I got my domain CNAME changed to azure service, I have to associate the azure web app with the address. When I try to do it I get the exclamation mark indicating error, and when I try to check what it says, it does not display any information (not a single sign). Does anyone experienced similar problem, and can tell me what is happening.</p>
