I bought one domain and assigned it to IP address with A record using Cloudflare.
Also, I changed registrar’s name server to CloudFlare DNS.
However, Firefox says
The page isn’t redirecting properly
Firefox has detected that the server is redirecting the request for this address in a way that will never complete.
This problem can sometimes be caused by disabling or refusing to accept cookies.
So, I deleted cookies but the problem still remains…
