Custom domain empty for SSL/TLS binding.

Question

In Azure web app, I have imported an app service certificate and it displays in the list. I then try and add a TLS/SSL binding but the Custom Domain dropdown list is empty. Any idea why that is?

@Si , Adding more info:

In the Azure Portal, go to your web app and navigate to the “Custom domain” section under “Settings”. Look for the domain you want to secure from the list of “Assigned Custom Domains” and click “Add binding”.

See, Tutorial: Map an existing custom DNS name to Azure App Service
And, just to confirm, did you purchase App Service domain or App Service Managed domain?

Kindly see the different between App Service Certificate and App Service Managed Certificate – each of these certificates can be used for different requirement:
