Hello, this morning I hooked up the domain under the Cloudflare, changed my dns and every 3 hours I checked the “Recheck Nameservers” button. Every time I wrote something was commissioned, and since morning I have not active nor dns or Cloudflare.
What’s your domain? Run a check with https://dnschecker.org/
Also, DNS propagation could take up to 48 hours (if you don’t have luck). Make sure you have the right settings too.
my domain is mineshop.pl
Your name servers are still from your default hosting when you should have Cloudflare’s NS instead:
