Delegated Servers from domain host are not connecting to azure

Question

I have successfully delegated my nameservers from the domain host (confirmed on whois), however it is not connecting correctly to azure (not reflected in a nslookup).

Answer 1

Thank you for your detailed response, Gitarani.

I have run nslookup and it confirms that the nameserver has been delegated:

        primary name server = ns1-02.azure-dns.com

However, when I go to the delegated domain, I receive this error:

     [DOMAIN]'s server IP address could not be found.

It would appear the issue is now IP address related

I have looked back in the Overview and Configuration of my azure Public IP Address, as well as its reference in the DNS Zone as a WWW A record, and do not see any obvious problems.

Any insight you have on this is greatly appreciated.

Hello @JohnMcCormick-9106 ,

You can use Azure DNS to host your DNS domain and manage your DNS records. For a successful domain delegation, you need to follow the below steps:

1. Create a DNS zone in Azure.
2. Retrieve name servers from the Azure DNS zone.
   **NOTE : When you copy each name server address, make sure you copy the trailing period at the end of the address. The trailing period indicates the end of a fully qualified domain name. Some registrars append the period if the NS name doesn't have it at the end. To be compliant with the DNS RFC, include the trailing period.
3. In the registrar's DNS management page, edit the NS records and replace the NS records with the Azure DNS name servers. Use all four name servers, regardless of the name of your domain.
4. After you complete the delegation, you can verify that it's working by using a tool such as nslookup to query the Start of Authority (SOA) record for your zone. The SOA record is automatically created when the zone is created. It can take a while for changes to propagate through the DNS system.

Could you please verify that you have followed all the above steps and the delegation is still not working? Also, please share the domain which you delegated to Azure.

I made it a step further after following this tutorial: https://learn.microsoft.com/en-us/azure/storage/blobs/storage-custom-domain-name?tabs=azure-portal#endpoint

which pointed out the need for a CNAME record linking the domain.

It now appears to connect, however this error is now results in the webbrowser:

<Message>The account being accessed does not support http. RequestId:b6f206f0-b01e-0029-1dc0-5ef075000000 Time:2020-07-20T18:06:19.6887797Z</Message>

Any insight on this?

Thank you, Gita.

After reviewing some other docs I was able to determine that I needed to disable the secure transfer. I had also been missing the CNAME record mapping the domain name to the azure website address.

Greatly appreciate your input on this.
