I'm trying to create a free App Service Managed Certificate for my Azure Web App using the feature that was announced yesterday at ignite (Secure your Custom Domains at no cost with App Service Managed Certificates).
I did add and verified a non-root custom-domain using a CNAME-Record. When I click on the button on the Create App Service Managed Certificates (Preview) dialog, I get the following error:
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.
Here is a screenshot of the error:
I tried this multiple times now, without success. Any ideas?
