Azure – Hostname Not Eligible for App Service Managed Certificates


I have an Azure App Service Plan shared by two App Services. For the first ( I have added an "App Service Managed Certificate". This has enabled secure requests to the site.

I've tried to configure the second app service ( in the same way but I get an error message that "Hostname not eligible".

Can anyone see where I've gone wrong please?

App Service Managed Certificates can only be used with URL's that are setup as DNS CNAME records. "" has been setup as an A record, not CNAME. You will need to delete the A record and create a CNAME record pointing to the app service DNS name.
