What 530 means

Cloudflare sends HTTP 530 alongside a 1xxx error page. The real diagnosis is the 1xxx number on the page: 1016 means Cloudflare could not resolve the origin hostname, 1033 means a Cloudflare Tunnel is not connected, and so on.

What typically causes a 530

Error 1016: a CNAME in Cloudflare points to a hostname that does not resolve.
Error 1033: cloudflared is not running or the tunnel is deleted/misconfigured.
Other 1xxx configuration errors on the zone.

Fix it on the server

Look up the 1xxx code in Cloudflare's docs; for tunnels, check cloudflared tunnel info and the connector logs.

Fix it as a client or visitor

Report the 1xxx code and Ray ID to the site owner.
