What is the name of the domain?
What is the issue you’re encountering
I setup the DNS on cloudflare by copying the complete record. Then I added the name servers with my hosting provider. DNSSEC was deactivated. Upon checking the name servers, I got the error message below. when I updated anyway, I was unable to connect via Mobile. Also Cloudflare complained “invalid nameserver” I had to revert the change so that the website started working again on mobile. It worked on desktop the whole time, though. Error message from Hosting provider (backtranslation) Are you sure you want to change the nameservers for your cantienica.com domain as follows? cullen.ns.cloudflare.com (checked) The specified nameservers do not provide an answer for the domain cantienica.com. Please make sure that the DNS zone of the domain is set up on the corresponding name servers. sneh.ns.cloudflare.com (checked) The specified name servers do not return an answer for the domain cantienica.com. Please make sure that the DNS zone of the domain is set up on the corresponding name servers. Please note that the domain has not yet been set up correctly on the new name servers. You can make the name server change, but we recommend that you first add the domain to your desired provider so that a DNS zone is created on the corresponding name servers and there is no interruption to your website or email traffic after the change.
