How can I troubleshoot an HTTP 522 error with Cloudflare?

Troubleshooting involves several steps. First, check your origin server's logs for errors. Then, verify Cloudflare's health checks are correctly configured and passing. Disable Cloudflare temporarily to see if the error disappears (this isolates if Cloudflare is the cause). Examine your server's firewall rules to ensure Cloudflare's IP ranges aren't blocked. Investigate potential issues with your server's application or code that might be causing slow or invalid responses. Finally, confirm your DNS records are properly configured and propagated.
