404 Error Code
What is a 404 error code?
A 404 error code is an Hypertext Transfer Protocol status response code (or HTTP status code) indicating that the page on a website a user is trying to reach can’t be found. In other words, while the server is reachable, the specific page can’t be reached. For example, the following is an example of a 404 error page from Pixar:
Users will typically receive one of the following error codes:
- 404
- 404 Error
- 404 Not Found
- 404 Page Not Found
- Error 404 Not Found
- File Not Found
- HTTP 404
- Page Not Found
- Server Not Found
Cause of a 404 error code
404 error codes typically appear because either:
- A user entered a URL incorrectly.
- The page the user previously accessed was moved or removed without redirecting users to the new page.
