Check What Is a 404 Error and How to Fix It?

Every time you try to access a link on the Internet or visit a website, you are actually telling a server to send you a page. This is called a request. The server then responds to your request by sending you a page back. And this communication system is known as HTTP. A 404 not found error is an HTTP status code that means the page you were trying to access could not be found on your server. Every time the web page is not found because it has a broken or dead link, a 404 web page not found is generated. This code has become one of the most well-known errors on the Internet.

When we communicate on computer networks via HTTP, a server is required to respond to a web-age request. In the code, the first digit indicates a user error. The error may be caused by an incorrect Uniform Resource Locator URL. The next two digits indicate the exact errors that occurred. The 404 code error message always comes with a human-readable “reason phrase” that anyone can understand. Most web browsers display 404 code error messages with the phrase “Page not found” as suggested by the HTTP specifications.

Definition of the dreaded 404 error

404 is an error code that appears on sites. This means that a connection is broken or does not display a substantial page on a site. It’s what all site owners disdain on their site that can ruin a customer’s web-based information. A customer can experience a 404 page in several ways. Maybe they followed a connection to the real site that causes a 404 error, or maybe they have a bookmark that causes a dead end. In some cases, 404 connections can also appear on other sites or through web crawlers.

Sites are discouraged from linking to numerous 404 pages due to adverse consequences on the end customer experience. Some web crawlers explicitly punish destinations that contain many broken joins. Incessant redirects to 404 pages can cause a site to be rated “poor” or “misleading” by Google’s calculations. Most happy management frameworks (CMS) have features that try to limit 404 traps.

Why “404”?

Why exactly is it 404? The first thing to realize is that there are other “numbers” that relate to the loading status of a web page. For example, if you load a normal web page, this is a “200 OK” request, which means it loaded without a problem.

Tim Berners-Lee, considered the father of the Internet, introduced HTTP status codes in 1992 during the World Wide Web Consortium (W3C). These codes, which are still in use today, are formatted as three-digit numbers. A code that starts with “4” means a client error, which means the user requested a page that he can’t access.

Here are some standard codes that also start with 4 that you might recognize:

  • 400 Incorrect Request: This typically appears when a bad request is made to the site.
  • 401 Unauthorized / 403 Forbidden: These appear when the user does not have the necessary permissions to access a page, such as a login or digital authentication.
  • 404 Not found: This appears when the resource or page does not appear to exist on the server.
  • 408 Request Timeout: This appears when the server timed out or reached its maximum time to load a page before the request finished.

Other common error messages

In addition to seeing “HTTP 404” or “404 Not Found”, you may also encounter some other error codes that say the same thing. Common variants are “page not found” or “file not found”. Depending on the website you are visiting, you may also see messages such as “Product not found”.

Keep in mind that websites can customize which page a 404 hyperlink points to. Therefore, many website owners design a custom 404 page. Some will ask you to contact the webmaster of the site; others use it as an opportunity for the user to search for something else on the site.
