Question
Cause of HTTP 404 Errors?

Answer

A 404 error is an HTTP status code that means that the page you were trying to reach on a website couldn't be found on their server.

Technically, an Error 404 is a client-side error, implying that the error is your mistake, either because you typed the URL in wrong or the page has been moved or removed from the website and you should have known.

Another possibility is if a website has moved a page or resource but did so without redirecting the old URL to the new one. When that happens, you'll receive a 404 error instead of being automatically routed to the new page.

Note: Microsoft IIS web servers sometimes give more specific information about the cause of 404 Not Found errors by suffixing a number after the 404 as in HTTP Error 404.3 - Not Found which means MIME type restriction. You can see a complete list here.

How To Fix the 404 Not Found Error

  1. Retry the web page by pressing F5, clicking the refresh/reload button, or trying the URL from the address bar again.

    The 404 Not Found error might appear for several reasons even though no real issue exists, so sometimes a simple refresh will often load the page you were looking for.
  2. Check for errors in the URL. Often times the 404 Not Found error appears because the URL was typed wrong or the link that was clicked on points to the wrong URL.
