Uptime Monitoring Error Codes

 

Here is a list of the most popular error codes and their descriptions that you can see in your Uptime Monitoring Dashboard:

200 — OK. The request to the server has succeeded. Everything is fine.

403 — Forbidden. The client does not have access rights to the content; that is, it is unauthorized, so the server is refusing to give the requested resource.

404 — Not Found. The server can not find the requested resource. In an API, this can also mean that the endpoint is valid but the resource itself does not exist. Servers may also send this response instead of 403 to hide the existence of a resource from an unauthorized client.

408 — Request Timeout. This response is sent on an idle connection by some servers, even without any previous request by the client. It means that the server would like to shut down this unused connection.

409 — Conflict. This response is sent when a request conflicts with the current state of the server.

500 — Internal Server Error. The server has encountered a situation it doesn't know how to handle.

502 — Bad Gateway. This error response means that the server, while working as a gateway to get a response needed to handle the request, got an invalid response.

503 — Service Unavailable. The server is not ready to handle the request. Common causes are a server that is down for maintenance or that is overloaded.

504 — Gateway Timeout. This error response is given when the server is acting as a gateway and cannot get a response in time.

508 — Loop Detected. The server detected an infinite loop while processing the request.

520 — Web Server Returns an Unknown Error. This error is essentially a catch-all response when something unexpected happens or when the origin server incorrectly interprets or does not tolerate a request due to a protocol violation or an empty response. It occurs when the connection started on the origin web server, but that the request was not completed.

521 — Web Server is Down. It happens when the origin web server refuses connections.
