How to assign my domain to ip adrress

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…
Any solution?


After changing SSL Flexible to FULL, enabled ALWAYS use HTTPS, Automatic HTTPS Rewrited, I finally could entered my domain page.
