Are you trying to move the domain between different Cloudflare accounts? With Cloudflare Registrar, you can’t change the nameservers away from those of the Cloudflare account the domain is registered in.
But that doesn’t make any sense and nobody told me when I transferred it here. Now I need to move it back to my other registrar. Such a scam cloudflare. My image of this company was good before. But now I can see they take advantage of their power. Scum.
Cloudflare’s Registrar service is given at cost price and it was clear to me from the documentation that it is only for domains using Cloudflare nameservers and the nameservers can’t be changed. It is an additional service for those already using Cloudflare and not generally for use by those who aren’t.
You can certainly transfer out after 60 days as per ICANN requirements.
