What is the meaning of Error 404 How to fix 404 error

Error 404 Sometimes when you know a page, you click on its link but instead of showing the result it shows a blank page with a message written on it ‘404 Not Found’. This 404 Not Found is an error message. This error message is a standard response code of HTTP (HyperText Transfer Protocol) in computer network communication.

404 not found means that the server was unable to find what was requested by the browser. This HTTP error code is followed by a human-readable message to make it understood to the end-user.

Error 404 not found should not be confused with DNS errors. DNS errors appear when a specific URL is given is of the server that does not exist, but a http error 404 appears when the server is found but is not able to retrieve the requested page.

In http status code 404, the first digit indicates client error and the remaining two digits indicate the specific error encountered. Some websites report a ‘404 not found’ error by returning a standard page with the status code 200 OK (200 OK is the code for successfully found page). Falsely reporting that the page has been loaded is known as soft 404. The term ‘Soft 404’ was coined in 2004.

What can cause 404 pages not found

Multiple reasons can cause a http status code 404. Some of them are listed below-

  • http 404 not found means that the server was unable to find what was requested by the browser.
  • If the server finds the requested information but the access is not granted, the server may send the response as 404.
  • The server sends a http 404 not found if the user attempts to browse a broken link.
  • 404 also occurs when the pages have been moved or deleted.
  • If the user types in the URL incorrectly, then also error 404 not found is thrown.
  • If the server responsible for the website is not running or the connection is not proper in such a scenario the server sends ‘404 Not Found’ error code.
