Error 521 | Webserver is down

Hi,

I am getting error 521 again and again. My site www.trueshayari.in not working on all countries. Many times its failed to load due to 521 (webserver is down). And sometimes its working as well.

I tried without cloudflare and site was working as well but whenever I am using cloudflare name-server and got back that error. Something is missing. Please help me.
I just want to resolve this issue.

Thanks

That would make me think that your web host is rate limiting or blocking some of the Cloudflare IP addresses, such as the ones in data centers nearest your visitor(s).
