nslookup fails after Azure DNS zone delegation for Azure-bought App Service Domain

Nick Claerhout 0 Reputation points


I have an App Service Domain that I bought on Azure and have been using for several years successfully.
However I recently deleted the DNS zone for this domain (accidentally, long story). I thought it was no problem and this can be recreated. So I go to the app service domain and click "Manage DNS records". It then asks for confirmation if I want to delegate to Azure DNS zone and I click yes. I get the following notifications:

  • "Successfully created DNS zone [mydomain.com]"
  • "Successfully updated the domain to use Azure DNS"

I can see an NS record and an SOA record.

Without any further configuration, normally I would be able to find this domain with the following command:
nslookup -type=SOA [mydomain.com]

However I can't find it and every time I try I see the message "can't find [mydomain.com]: Server failed".
I understand setting this up would be slightly more difficult for a domain purchased from an external provider, but since this is bought on Azure and the steps are really straightforward I don't understand.

I have added a screenshot below.

    Hi Nick,

    If you perform a whois from a registrar on the Internet does your domain show with the name servers pointing to Azure DNS? For example, browse to whois.com and enter your domain in the box in the upper right corner.

    I leaning towards you needing to open a new support request in the portal so that they can manually fix it for you.
