I can’t connect anymore with my dns entry https://teamvace.de since I changed the nameservers to the cloudnet nameservers. I think its a nameserver error (this was the answer of my hoster and I should contact you) so i think somewhere in the change cloudflare got a problem anyone help?
Where did you get the nameserver pair you entered for Cloudflare? Not from the Cloudflare UI. Your zone is not active on Cloudflare under your account and is pointing to incorrect Cloudflare nameservers at your registrar.
