Content for NS record is invalid. ns records at the apex must not overwrite assigned nameservers
What is the issue you’re encountering
Changed primary iCloud email associated with domain. Instructed through Cloudflare to update NS. Unable to locate or delete NS and add new NS.
What steps have you taken to resolve the issue?
Attempted to add new NS details, but received error message. Searched all of Cloudflare support content to resolve, still unable to locate where the former NS can be deleted to add new. Uncertain whether Cloudflare handles this change on their end.
What feature, service or problem is this related to?
NS lookup shows still being linked to former servers used in initial account set up, but getting these instructions. Registrar was always Cloudflare. Sounds like i need to put in a ticket.
I’m afraid this is known to cause problems like the one you’re describing. The iCloud login seems to lose its relation with the Cloudflare account on such changes.
