I have an Azure App Service with a single Deployment Slot.
I have added a custom domain name that I created at an external registrar.
When I go to configure TLS/SSL bindings, and select "Managed Certificate" and validate, the validation succeeds with the following message:
Hostname eligible for App Service Managed Certificate creation. Please note that it might take up to 10 minutes for App Service Managed Certificate to be issued.
Finally, I click "Add" and am immediately met with the following error:
Failed to create App Service Managed Certificate for my.custom.domain due to error: The Resource 'Microsoft.Web/certificates/my.custom.domain-slotname' under resource group 'my-rg' was not found. For more details please go to https://aka.ms/ARMResourceNotFoundFix
The information at ARMResourceNotFoundFix is not helpful.
Creating the managed certificate for the non-slot worked perfectly.

2022-10-31T19:54:43.227+00:00 I was able to get this to work using the AZ CLI https://learn.microsoft.com/en-us/cli/azure/webapp/config/ssl?view=azure-cli-latest#az-webapp-config-ssl-create
I would really like to see this fixed in the portal though.

Based on the shared information we have understood that you are trying to create Managed certificate (free) to secure your customer domain by binding this certificate to webapp. Could you please check whether the created certificate and the webapp are in the same resource group?
Could you please retry the operation by following this documentation steps on how to create a free managed certificate and to secure your custom domain with this certificate, you have to create a certificate binding. Follow the steps in Create binding.
Feel free to reach back to me if you have any further questions on this.
