CDN Error Codes

Updated on April 14, 2022

Error pages will not be cached, therefore only 200, 301, and 302 responses will be cached. KeyCDNs error pages show either a black or blue error code font color. All other error pages are coming from your origin server.

400 Bad Request

In most of the cases a malformed HTTP request (e.g. empty requests by load balancers / health checks). A certain number is normal. Learn more about how to avoid a bad request.

403 Forbidden

It is prohibited to access the requested asset. A possible reasons is a wrong URL or the Secure Token is not valid. Learn more about 403 Forbidden errors.

404 Not Found

The content either does not exist or has been moved. Learn more about 404 Not Found errors.

405 Method Not Allowed

The method is not allowed. A Push Zone only supports the GET and HEAD methods. Learn more about 405 Method Not Allowed errors.

410 Gone

The Secure Token has expired.

A bad bot which is blocked hits a KeyCDN edge server.

500 Origin Error

Our edge server was not able to pull the content from your origin server. Either your origin server is not reachable or firewall rules prevented the connection. The status code 500 is a generic error message, which is thrown if there is a 502 Bad Gateway or a 504 Gateway Timeout.
