2weeks haven't solve 521 error with vps

Hi community cloudflare , i am facing big problem since two weeks :frowning: . I have upgrade my hosting plan and When i activate cloudflare on my website :info-ideal.com,i got error 521 and when i paused cloudflare website work fine .
I have contacted namecheap support and after 2 hours of assistance they told me to contact you and provide link to this thread to help your support to solve my situation :

Second , they and i , we are pretty sure that these common causes are properlly checked :

  • changing ip adressess in dns section : done
    Ensure your origin web server is responsive
    Review origin web server error logs to identify web server application crashes or outages.
    Confirm Cloudflare IP addresses are not blocked or rate limited
    Whitelist all Cloudflare IP ranges in your origin web server’s firewall or other security software

Please fix my issue as i told you before i have more then 2 weeks facing this issue

All helps are appreciated.
Thank you for your coorporation.

As a Community member, I can not fix this issue for you…only offer suggestions.

I get your site once, and when I reload, I get a 521.

I see you’re running Railgun. Is there a way you can turn that off while you troubleshoot?
