As a website owner, encountering errors is an inevitable part of the online experience. One common type of error is the 4xx error, which indicates that there was an issue with the request made by the client. In this article, we will take a closer look at the different types of 4xx errors, their causes, and how to fix them.
What is a 4xx error?
A 4xx error is a client-side error that occurs when a user tries to access a web page, but the server is unable to fulfill the request. The error message indicates that there was an issue with the request made by the client, such as a bad request or unauthorized access.
Common types of 4xx errors
Here are the most common types of 4xx errors you might encounter:
400 Bad Request
The 400 Bad Request error occurs when the server cannot understand the request made by the client. This error can occur due to a malformed URL, missing parameters, or invalid data.
The 401 Unauthorized error occurs when the client attempts to access a page that requires authentication. This error can occur when the user enters incorrect login credentials or when the page requires a password.
The 403 Forbidden error occurs when the server denies access to the requested page. This error can occur when the user tries to access a page without proper permissions, or when the page has been removed or blocked by the server.
404 Not Found
The 404 Not Found error is one of the most common 4xx errors and occurs when the requested page cannot be found on the server. This error can occur due to a broken link or when the page has been deleted or moved.
408 Request Timeout
The 408 Request Timeout error occurs when the server takes too long to respond to the client’s request. This error can occur due to network issues, server overload, or slow internet connection.
The 410 Gone error occurs when the requested page has been permanently removed from the server and will no longer be available. This error can occur when a website is shut down or when a page is deleted permanently.
