Am having the same issue, I have SSL on my site from Let’s Encrypt but anytime I enable Cloudflare it gives me 521 Host Error. When I pause it, everything starts to work sometimes I see the cpanel 404 page. Don’t know what to do again

A screenshot to your host? Maybe, depends what they need. You could also open a support ticket with Cloudflare and maybe they can shed some light on what is going on from their perspective. https://support.cloudflare.com/requests/new - if you open a ticket post the number here @cloonan
