502 bad gateway error cotazur.it

why I have a 502 bad gateway error on my website: www.cotazur.it ?
I set DNS zone correctly and my host can’t resolve the problem cause said it is from Cloudflare.
can someone help me?
I paused Cloudflare now.


The 502/504 errors are caused by a problem connecting to an upstream server - meaning your server is trying to initiate a process and this fails to work as expected or times out. In most cases of 502 / 504 errors, back-end servers are not communicating correctly. When this happens, you will see color page with Cloudflare branding and the Error 502 Bad Gateway or Error 504 Gateway Timeout. Review this Community Tip for fixing 502 or 504 gateway errors.
