You have a mixture of nameservers that produce different answers: 172800 IN  NS 172800 IN  NS 172800 IN  NS gives a good, valid IP address.

The OVH ones say that you don’t have any IP addresses.

I think you will want to login to your OVH Domain Registration interface, and remove the OVH nameservers from the domain.

Great, thank you @_az :slight_smile:
I followed a few day the query of OVH to change the DNS for this domain.
I just provided the “old” DNS and that fixes the issue.
