Fix Cloudflare Error 522 – Connection Timed Out & Origin

Quick answer: Cloudflare 522: make origin reachable (web service running, correct A record IP), don't block Cloudflare in firewall and check SSL mode (Full).

If you landed here: Browser shows "Error 522 – Connection timed out" with Cloudflare branding – site or subdomain unreachable.

5-minute checklist

1. Test origin by IP directly – is web server running?
2. Cloudflare DNS: A record points to current server IP?
3. Server online? nginx/Apache + PHP-FPM active?
4. Test grey cloud (DNS-only) temporarily – does it work?
5. SSL/TLS: Full (strict) if origin certificate exists
