I am the sysadmin for that domain, the situation is as follows:
Almost a week ago we registered this domain on cloudflare, we were given isaac and rose as NS Servers, i went to change the records in the DNS (OVH Control panel) and to my surprise it simply refused to update the default values to the ones provided by cloudflare, i then tried again thinking “ok i might have done something wrong” but again same failure to update the NS records for that domain. We opened a support ticket with OVH right away and the reply was to check what was wrong using the tool in this page (https://dns-check.nic.it/), After checking the results of that tool we noticed that somehow we have kanye and may as NSCompare.
My conclusion is the following: someone (or one of our staff or someone else) registered that domain in their account before we did resulting in this stale situation (we cannot find any other account registered on cloudflare with our domains email accounts).
Is there any way to manually change the NS servers back to kanye and may (provided we give proof of ownership for that domain) so we can edit our dns records to match those of the registar.
The only other solution we are left with is erase the domain from our cloudflare account and adding it back again untill the 2 NS servers assigned are again kanye and may but i do not think that is the wised solution (so far OVH only dropped the ball back to us on the support ticket and apparently it is going to end the same way here)
