Domain in zone DE.
Added to Cloudflare and configured NS at the registrar.
I deleted the domain from the old account and added it to the new account Cloudflare.
All settings are the same.
I can’t change the NS at the registrar, the error is: “Name servers for DE domains must respond to DNS queries for the domain before being set.”
I checked NS settings in a special service: https://www.denic.de/en/service/tools/nast/
Errors are as follows:
I have several domains in the DE zone, the registrars are different and I can not change the NS for everyone.
