Unable to apply SSL Binding in Azure to Web App Service

Question

I've imported a Private Certificate through Azure which it's given a status of healthy so assume all the verification is correct. However when I try to add an SSL Binding I'm not given any options in the Hostname.

I'm following the tutorial below and my experience in the 'Bind certificate to app' section

https://docs.microsoft.com/en-us/azure/app-service/web-sites-purchase-ssl-web-site

Certificate looks to have been imported:

No binding options:

I've added a custom domain which has validated but I still don't have the option.

Answer 1

You have to add a domain or hostname first to be able to add binding.
