Invalid nameservers

What is the issue you’re encountering

When I try registering some GoDaddy domains that have the correct Cloudflare nameservers, I can’t get past the initial setup prompts… Cloudflare keeps mentioning that I need to set the correct nameservers… I’ve set them but no updates.

Remove the domain / Re-add the domain
Change namesrvers on GoDaddy

What feature, service or problem is this related to?

Nameservers

Register GoDaddy domain
Add domain to cloudflare
Update Nameservers as instructed
Wait 1 billion years
Even if the nameservers are correct, I still get the same error

You have a DNSSEC issue…

You need to either disable DNSSEC at your registrar, or enable it at Cloudflare and copy the DS records to your registrar from your dashboard here…

Thanks - after going through support on GoDaddy’s side and concluding that DNSSEC wasn’t enabled, I’ve enabled in on Cloudflare’s side and copied the DS records across as instructed… Lo an behold that when clicking save on GoDaddy, a couple of phantom DS records appeared.

Deleted those, confirmed the Cloudflare DS record, hit submit and all is now resolved.

Thanks again!

I should add that these domains were old Google Domains hosted, so have hopped from Google Domains → Squarespace → GoDaddy… no surprise that something has been maligned along the way.
