title: Failed to create App Service Managed Certificate
body: <p>I'm trying to create a <strong>free App Service Managed Certificate</strong> for my Azure Web App using the feature that was announced yesterday at ignite (<a href="https://azure.microsoft.com/en-us/updates/secure-your-custom-domains-at-no-cost-with-app-service-managed-certificates-preview/" rel="nofollow noreferrer">Secure your Custom Domains at no cost with App Service Managed Certificates</a>).</p>
  
  <p>I did add and verified a non-root custom-domain using a CNAME-Record. When I click on the button on the <em>Create App Service Managed Certificates (Preview)</em> dialog, I get the following error:</p>
  
  <blockquote>
    <p>Failed to create App Service Managed Certificate for hostname
    xxx.yyy.com Error Details: The gateway did not receive a response
    from 'Microsoft.Web' within the specified time period.</p>
  </blockquote>
  
  <p>Here is a screenshot of the error:

  <p>I tried this multiple times now, without success. Any ideas?</p>
