Cannot delete or update some Azure DNS zone entries

Question

I recently updated an Azure public DNS zone entry adding a new IP into A record.

Now I'm trying to remove that IP address from the entry, but when trying to edit it from Azure Portal, I get this message: "Failed to save record set '{record_name}'. Error: There was an error processing your request. Try again in a few moments."

When trying to delete it, I get this message: "Failed to delete record set '{record_name}'. Error: There was an error processing your request. Try again in a few moments."

Azure activity log shows:

Error code: InternalServerError
Message: {"code":"InternalServerError","message":""}

I also tried to use Azure CLI and Az PowerShell, but the result was the same.
I wait more than two days with no DNS zone changes, but the problem persists.

At the same time, I can add and delete some other entries in the same DNS zone.

Could someone help me please?
Thank you

Hi,

Just check if the IP is not associated with any other resources like App Gateway or VPN services or VM? If it is not and still you cannot delete or update I will suggest you to raise a support case with Microsoft as the IP is locked and can only be deleted or modified from the backend.

Hope this helps.

The problem was solved after contacting Azure support. The problem was on the Azure side, they solved it and deleted the problematic entries.

Resolution:

• Initially, you had contacted us to check the DNS record deletion issue.
• We checked the details from the backend and requested to delete with PowerShell and CLI.
• Later, we investigated the logs as per the error timeframe and performed delete operations.
• We involved our PG team to fix the issue from the backend, and they worked and mitigated the issue.
