Cloudflare error 530
Cloudflare could not resolve or reach the origin; the page shows a second, 1xxx error that names the reason (1016: origin DNS error is the most common).
Where it failed: the origin behind Cloudflare
What visitors see
Cloudflare's error page with code 530 and a 1xxx error number.
Usual causes
- Error 1016: the origin is a CNAME to a name that does not resolve.
- A deleted or renamed origin (a removed tunnel, a removed load balancer).
- Cloudflare Tunnel (cloudflared) is not running.
How to tell which one it is
- Read the 1xxx number on the page; Cloudflare's documentation lists each one.
What to do
- Fix the CNAME target or replace it with the origin's IP.
- Restart cloudflared if the site runs through a tunnel.
