One.com not accepting Cloudflare nameservers

Hello, my Provider one.com says the cloudflare Nameservers are not correct.

One.com says the problem is at cloudflare but i my cloudflare is setup correctly.

Does someone have any tips?

Your domain isnt using Cloudflare at all. It also doesnt seem to be set up on Cloudflare.

i set it up correct on cloudflare.

Your screenshot said magazin.de, not pixel-magazin.de.

Anyhow, Cloudflare doesnt seem to know about that domain either. Can you post a screenshot of the nameservers on your DNS screen on Cloudflare?

here they are

Interesting, neither of both nameservers accept your domain.

You probably should open a support ticket in this case.
