Unable to delete custom domain from static web app

WRex 0

I recently attempted to delete a custom domain from an Azure static web app. It has been stuck in the deleting status for several weeks. I've attempted to delete it from the GUI multiple times over the course of the past few weeks.

All DNS records for the custom domain (CNAME, etc) are still active.

I've also attempted to run the following PowerShell command (with the correct names for each variable):

$rg = "[resource group name]";
$name = "[static web app name]";  
$remove_me = "[custom domain name]";  
$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!";

As well as this by itself:

Remove-AzStaticWebAppCustomDomain -ResourceGroupName [resource group] -Name [static web app] -DomainName [custom domain name]

Neither has worked, with the logs showing:

As well as this in PowerShell:

Remove-AzStaticWebAppCustomDomain_Delete: The server responded with an unrecognized response, Status: OK

Any assistance would be appreciated in resolving this.

Hi @Wrex ,
Thanks for reaching out to Microsoft Q&A.
As your description, your custom domain is stuck in the deleting state for several weeks. Even after multiple retries using the Azure portal and PowerShell commands, it remains undeleted.
Remove DNS Records Before Deleting Before attempting another delete operation, ensure that all DNS records (CNAME, TXT) associated with the domain are removed from your domain registrar.

Use Azure CLI to Force Delete Try deleting the custom domain using Azure CLI, as it may bypass UI-related issues,
az staticwebapp hostname delete -n "<static-webapp-name>" -g "<resource-group>" --hostname "<custom-domain>"
Use PowerShell Script (Retry Delete Until Success) If the CLI fails, use a PowerShell loop to keep retrying the deletion until it succeeds.

$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!";

Give Deleting a Shot via Azure Resource Explorer

Open it up

Head to: subscriptions/{subscription-id}/resourceGroups/{resource-group}/providers/Microsoft.Web/staticSites/{static-web-app-name}/customDomains/{domain-name}

Try deleting the domain manually.

Look for Azure Resource Locks If your Static Web App or resource group has a delete lock, remove it by going to: Azure Portal > Resource Group > Settings > Locks

I've attempted to delete it from the Azure Resource Manager as well as manually, but it did not work.

The resource group currently has no locks in place.

When using the command you provided (with correct information):

az staticwebapp hostname delete -n "<static-webapp-name>" -g "<resource-group>" --hostname "<custom-domain>"

I get the following output and the custom domain isn't deleted:

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. (Unspecified) Code: Unspecified Message:

The script I ran originally came from the forum post you linked.

I am in the process of removing the DNS entries.

Hi @Wrex ,
Thanks for the update!
It looks like the deletion attempt hit an unspecified error, probably because of existing DNS records. Make sure to remove all DNS records (CNAME, A, TXT, etc.) related to the custom domain from your DNS provider. After deleting the records, wait about 15-30 minutes for the changes to propagate.

Then, try deleting the custom domain again using this command:

az staticwebapp hostname delete --name "<static-webapp-name>" --resource-group "<resource-group>" --hostname "<custom-domain>"

If the issue persists, check Azure Resource Explorer (resources.azure.com) to see if the custom domain entry still exists. If it does, try manually removing it from there.

Sometimes, Azure takes a bit to fully process domain removals. If the domain isn't deleted after retrying, wait a bit longer and check again.

DNS entries were removed, but the custom domain is still stuck "deleting" in the portal.

Hi @WRex
Thanks for your update.
Could you please try deleting the custom domain using either of the cmdlets az staticwebapp hostname delete or Remove-AzStaticWebAppCustomDomain? Alternatively, you can also use the REST API to delete the custom domain of the static webapp.
After using the az command then also you are facing same issue then you can try this.
you can use the below PowerShell script to delete custom domain of static web app this script will retry the delete operation until it gets succeeded. You can run this script from cloud shell in the portal if you don't have PowerShell locally installed.

$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 @brtrach-MSFT answer using azure resource explorer as mentioned in this similar thread
