We use a niche domain extension and the people who manage it, evidently, take months to make changes to nameservers. It took >45 days for them to update the nameservers to cloudflare's, at which point, unbeknownst to us - cloudflare had already deleted the domain.
No worries - we thought, since the email that got lost in our inbox said "we’ll re-apply the configurations you had before" if we just go back and add the domain in again.
However, when we added the domain back in cloudflare – the required nameservers were different. This seems unintended. Is there any way to work with cloudflare support or configure something different so that this domain's name servers go back to what they were originally?
