If error 1019 appears after a Worker deployment or route change, trace where its outgoing request goes.

Cloudflare error 1018 means the host could not be found. Begin with when the domain was activated and whether Cloudflare was connected directly or through a hosting partner. Cloudflare documents activation propagation and partner DNS failure as possible causes.

With Cloudflare error 1016, the visitor reaches Cloudflare but Cloudflare cannot resolve the origin server’s IP address. Check the affected hostname’s configured origin record and any CNAME target against the host’s current instructions. A record can exist while its target no longer resolves, especially after a provider migration. Guide reviewed: October 8, 2026. Interface labels … Read more
If Cloudflare error 1015 appears while browsing or using a feature, stop rapid retries and keep the failed address and time. The site owner sets the visitor rate-limiting rules. Owners should compare the matched rule with the actual request pattern, including background requests a single visible action can generate. Guide reviewed: October 8, 2026. Interface … Read more
Cloudflare error 1014 can mean a CNAME points to a domain in another Cloudflare account without a supported connection. Check the actual target and the provider’s custom-domain instructions.

If an image works on your WordPress article but fails on an external page with Cloudflare error 1011, inspect the image request and hotlink policy before uploading another copy.

Cloudflare error 1010 concerns a browser or client signature blocked by the site’s security settings. Identify the client that failed and report its request context. A monitoring service, integration and ordinary browser can send different headers; a successful browser visit alone does not resolve an integration failure. Guide reviewed: October 8, 2026. Interface labels may … Read more
Cloudflare error 1009 means the site has denied access from a country or region associated with the request’s IP address. The owner’s connection may still work.
