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?

Frequently asked questions (FAQ)

Cloudflare 522 – what does it mean?
Cloudflare can't reach your origin server (timeout). Server offline, wrong A record IP, firewall blocking Cloudflare IPs or web service (nginx/Apache) not running.
522 only with orange cloud (proxy)?
Yes – test DNS-only (grey cloud). If it works then: firewall must allow Cloudflare IP ranges or adjust SSL mode (Full vs Flexible).
522 after DNS migration?
Set A record in Cloudflare to new server IP, start origin service, wait 5–15 min. Check propagation with dnschecker.org.
