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.
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?
Interesting, neither of both nameservers accept your domain.
You probably should open a support ticket in this case.
