My Azure Web App couldn't find a valid certificate

Question

I created an app managed certificate within the TLS/SSL section of Azure for a Web App and used the bindings section to link it to a custom domain. Now when I publish my app, it launches with the following error (from event logs):

System.InvalidOperationException: Couldn't find a valid certificate with subject 'CN=interax' on the 'CurrentUser\My'
