title: Azure Frontend door shows "Our services aren't available right now " with service fabric cluster
body: <p>I have set up an Azure Frontdoor in azure portal. I've created </p>
  
  <p>2 frontend host </p>
  
  <ol>
  <li>myappdev1.azurefd.net </li>
  <li>dev1.myapp.com </li>
  </ol>
  
  <p>Baackendpool with the following</p>
  
  <p>1.BackendHostName= myappdev1.northeurope.cloudapp.azure.com
   2.Backendhostheader= dev1.myapp.com 
   3. HTTPS port 62652</p>
  
  <p>and the Routing rule</p>
  
  <p>with a https routing rule mapping both frontend to backend with HTTPS only.
  myappdev1.northeurope.cloudapp.azure.com is a service fabric cluster with a web application deployed on port 62652 so the url <a href="https://myappdev1.northeurope.cloudapp.azure.com:62652" rel="nofollow noreferrer">https://myappdev1.northeurope.cloudapp.azure.com:62652</a> works.</p>
  
  <p>I've also mapped dev1.myapp.com to myappdev1.azurefd.net in a CDN</p>
  
  <p>But on running either  <a href="https://myappdev1.azurefd.net" rel="nofollow noreferrer">https://myappdev1.azurefd.net</a> or <a href="https://dev1.myapp.com" rel="nofollow noreferrer">https://dev1.myapp.com</a> </p>
  
  <p>i get an error</p>
