"Can't find auth dns server for example.co.uk"

Hi all,

I have recently created a subdomain and did a basic DNS health check (if it’s called that) on DNSChecker.Org.

It came back with a warning saying "Can’t find auth dns server for (my subdomain.co.uk). I was wondering why this has occurred and if there is a simple fix?

Would appreciate any insight into this matter. I saw that someone else asked a similar question a few days ago but I did not see a solution.

Many thanks

What is the domain and subdomain?

slat_eo.co (I placed an underscore as it linked the website into the comment)

edu.slateo.co (subdomain)

Your domain has an SOA…

Your subdomain doesn’t as it doesn’t use delegated nameservers. Querying the SOA for the subdomain will return the SOA for the domain…

Interesting - with all honesty, this does not make much sense to me as I do not come from a very technical background.

Could you advise if I need to update certain DNS records and if so, what these records would be?

I would be very grateful!

There’s nothing you need to do. This is the way DNS works. Any SOA records needed are created automatically by Cloudflare.

Okay, I understand.

So this error message that occurred on DNSChecker.org is not serious and I can ignore it?

Yes, it’s not an error and you can just ignore it.
