What is the issue you’re encountering

About 15 days ago, many customers started reporting that they were receiving error 522. The problem does not occur with all customers, but with a small portion of them. After researching the error here in the community, I decided to open a ticket on my hosting server to ask them to check if all Cloudflare ranges were open. I received feedback that there is no active firewall and that no blocking is being performed by the hosting server. Now I don’t know how to fix this problem. Could someone help me?

Hello, most common cause is some portion of Cloudflare IP addresses :arrow_upper_right: are rate limited or blocked in .htaccess, iptables, or firewalls. The easiest way to see it is by looking at the CF-Ray header’s last 3-letter code, which refers to the colo at the 522 error. If the 3-letter code is consistent for every 522 error, it is likely that some portion of the Cloudflare IPs is being blocked.
