Are you sure you want to perform this operation? (y/n): y
After deleting a custom domain, there can be a 15 minute delay for the change to propagate.

Same issue, slightly different cause.

I did a terraform destroy on a static web site 3 days ago. It failed and 72 hours later the custom domain is still showing as "deleting". One thing that might be significant is that the domain was never verified.

Don't know exactly what a terraform destroy is, but I moved all my other resources to a new resource group and then deleted that static app after recreating a similar one and setting deployment to that. Seems to have finally done the trick, but obvs not ideal.

Terraform is just a templated way of creating the Azure resources, under the hood it's just using the az cli I believe.
A week after the deletion was requested the custom domain is still showing as "Deleting" in the UI and from the az command line.

For the curious the "unknown error" is the domain verification timing out because of a typo in the domain.

Any feedback from @VenkateshDodda-MSFT would be appreciated as I would rather not go down the scorched earth route if at all possible!

@Mike Rogers custom domain binding operations should take normally around 20 minutes. Overall, TXT record validation and DNS record propagation will affect this amount of time but around 20 minutes should be the expected norm. If the custom domain deletion operation is failing or taking longer than expected, the workaround is to re-try the delete operation until get succeeded using the below PowerShell script.

 $name = "<static-webapp>";  
      $remove_me = "sub.domain.com";  
      $domains = Get-AzStaticWebAppCustomDomain -ResourceGroupName $rg -Name $name;  
      $len = $domains.Length;  
      while($len -eq $domains.Length){  
              foreach($item in $domains){  
                  if($item.name -eq $remove_me){  
                      $err = Remove-AzStaticWebAppCustomDomain -DomainName $remove_me -Name $name -ResourceGroupName $rg -NoWait;  
                      $domains = Get-AzStaticWebAppCustomDomain -ResourceGroupName $rg -Name $name;   
                      if($domains.Length -gt 0){  
                          Write-Host "$remove_me still exists. Retrying...";  
                          Start-Sleep -s 10;  
                      }  
                  }  
              }   
          }  
      Write-Host "Success!";

If you want to delete the static web app you refer to @Anonymous answer using azure resource explorer as mentioned in this similar thread Static Web App custom domain does not delete - Microsoft Q&A.If you still face the issue i would suggest you to open a new thread in Microsoft Q&A here and tag appropriate Service labels so that relevant SME can assist on it.

Thanks,

I was sceptical, having already tried the PowerShell route without success, but your script did the trick after about half an hour.

I guess Azure just needs to be told the same thing a lot!

This script worked for me to remove the custom domain. Warning it can take a while!

   $name = "yourstaticwebapp";  
   $rg = "yourresourcegroup"  
   $remove_me = "yourcustomdomain";  
   $domains = Get-AzStaticWebAppCustomDomain -ResourceGroupName $rg -Name $name;  
   $len = $domains.Length;  
   while($len -eq $domains.Length){  
           foreach($item in $domains){  
               if($item.name -eq $remove_me){  
                   $err = Remove-AzStaticWebAppCustomDomain -DomainName $remove_me -Name $name -ResourceGroupName $rg -NoWait;  
                   $domains = Get-AzStaticWebAppCustomDomain -ResourceGroupName $rg -Name $name;   
                   if($domains.Length -gt 0){  
                       Write-Host "$remove_me still exists. Retrying...";  
                       Start-Sleep -s 10;  
                   }  
               }  
           }   
       }  
   Write-Host "Success!";

In order to delete a custom domain mapping from your app, your account must have the App Engine Admin role (roles/appengine.appAdmin) or a custom role that contains the appengine.applications.update permission.

In the Google Cloud console, do the following:

Go to the Custom Domains tab of the App Engine Settings page.

Go to the Custom Domains page

Select the custom domain name and click Delete.

Alternatively, you can use gcloud commands or the Admin API to delete custom domains.
