By whitelisting Cloudflare's IPs, you allow the necessary network communication to flow smoothly between Cloudflare and your origin server. Whitelisting Cloudflare IPs ensures that legitimate traffic from Cloudflare's network can reach your website without hindrance, effectively resolving the 522 error
