When you see the error DNS PROBE FINISHED NXDOMAIN, it means a domain cannot be resolved because of an issue with the DNS servers, the domain name is newly registered, or the domain is not yet registered at all. First verify the domain is pointed to Cloudflare name servers. If not, contact your domain registrar and ask that they point the domain to your Cloudflare nameservers and wait an appropriate amount of time for DNS propagation to take effect.
