Our registrar doesn’t allow to add the cloudflare nameservers and upon contacting them they told us that the issue is at cloudflare level and provided the following zonecheck report :
According to the registrar, cloudflare DNS fails to comply with the requirements for DNS servers .
Personally I have added quite a few domains to cloudflare and never saw this happening before but the registrar enforces there is nothing they can do on their side .
Is this really some issue at cloudflare level ? How can this be fixed ?
