i have this in my notes, glad if it is of any help, keepalive is the only one i’ve ever had issue with
When someone visits a Cloudflare-enabled website, a connection is established between Cloudflare and the website’s origin server. To establish a connection, TCP uses the three-way handshake shown as follows:
Cloudflare sends three SYN packets to the origin server.
In response, the origin server replies with a SYN+ACK.
Finally, Cloudflare sends an ACK back to the origin server.
But the error 522 connection timed out will occur, if the following 2 cases happen:
Before a connection is established, the origin web server does not return a SYN+ACK to Cloudflare within 15 seconds of Cloudflare sending a SYN.
After a connection is established, the origin web server doesn’t acknowledge (ACK) Cloudflare’s resource request within 90 seconds.
Then, what causes the error 522? The possible reasons are as follows:
Cloudflare IP addresses are rate limited or blocked in .htaccess, iptables, or firewalls. Confirm your hosting provider allows Cloudflare IP addresses.
An overloaded or offline origin web server drops incoming requests.
Keepalives are disabled at the origin web server.
The origin IP address in your Cloudflare DNS app does not match the IP address currently provisioned to your origin web server by your hosting provider.
Packets were dropped at your origin web server.
