Alright, so I'm trying to use WHMCS and in order to run on https I have to have my SSL set to Full in CloudFlare. This would be fine if the site didn't crash. It works fine if I connect directly to the IP, but when I connect via the domain name it doesn't work. I get a 521 server error.
I am using CentOS 7 and I installed firewalld. I whitelisted the IP addresses that CloudFlare has.
firewall-cmd --get-active-zones
public
sources: 173.245.48.0/20 103.21.244.0/22 103.22.200.0/22 103.31.4.0/22 141.101.64.0/18 108.162.192.0/18 188.114.96.0/20 197.234.240.0/22 198.41.128.0/17 162.158.0.0/15 104.16.0.0/12 172.64.0.0/13 131.0.72.0/22
These are all the IPs listed on Cloudflare's website. I have tried rebooting the firewall, rebooting Apache, and even rebooting the server and I still get a 521 error. What am I missing? I have tried everything on their help page that can be seen here: https://support.cloudflare.com/hc/en-us/articles/200171916-Error-521-Web-server-is-down
