What Are 5xx Server Errors and How to Get Rid of Them? - MiniTool

When the server cannot complete the client request, a 5xx server error will be returned. This article will list various 5xx error codes and their brief explanations and guide you on how to fix 5xx server errors.

The HTTP status code is the server's response to a client request (browser or search engine). These codes consist of three numbers indicating whether a specific HTTP request was successfully completed. The first number (range from 1xx to 5xx) defines the category of the response:

1. Information Response (100-199)
2. Success (200-299)
3. Redirect (300-399)
4. Client Error (400-499)
5. Server Error (500-599)

What is a 5xx server error?

The 5xx code appears when the server does not support the functionality required to process visitor requests. Simply put, the server has a failure. In most cases, the problem arises from server overload, network errors, web server issues, or an error while performing an HTTP request.

5xx Status Code

The following is a list of 5xx server error codes and a brief description:

500 – Internal Server Error

This is a common error message indicating that there is a problem with the website server, but the server cannot specify the problem.

501 – Not implemented

The server running the website does not understand or supports the HTTP method sent by the client. This code usually implies future availability.

502 – Error Gateway

This code indicates that the server acting as a gateway or proxy has received an invalid response from the upstream server.

503 – Service Not Available

The server cannot process the request due to temporary overload or maintenance of the server. When this code appears, Google understands that you have a temporary problem and will not punish your website or unindex your page.

504 – Gateway timeout

The server does not receive a response from another server acting as a gateway or proxy in a timely manner and cannot complete the client's request within a given time frame.

505 – HTTP version is not supported

This error occurs when the server does not support the HTTP protocol version used in the browser request.

506 – Variants are also negotiating

This code indicates an internal server configuration error. The server detects a circular reference while processing the negotiated portion of the requested content.

507 – Insufficient storage space

This status code is returned when the server cannot create or modify the requested resource due to insufficient available storage space. As with the 503 server error, this is a temporary situation.

508 – Loop detected

This error occurs when the server tries to process the request and discovers an infinite loop. This code indicates that the entire operation failed.

510 – Not expanded

The browser does not understand the necessary extensions required for the request.

511 – Requires network authentication

This error occurs when the client (browser) needs to authenticate to access the network. The response indicates that the link should contain a link to the resource that allows the user to send their credentials.

How to fix 5xx server errors

Here is how to fix 5xx server errors:

1. Check the server's error log. By performing log file analysis, you can get more information about the error status code.
2. Make sure your server is not overloaded or misconfigured. In this case, you need to consult your developer or contact your hosting provider.
3. Check out your recent changes to see if there are any reasons that might cause the error. Sometimes plugin problems (such as installation errors or incompatibility) can lead to errors. Deactivate the plugin and check if the error disappears. In this case, activation of the plugin one by one to detect which plugin is causing the problem.
