Error 404 means that the page you requested cannot be found on the server. The HTTP status code 404 is usually returned by the server when the client (in this case, your web browser) sends a request to a URL that does not exist or is inaccessible.

Error 404 can occur for several reasons:

Incorrectly typed or specified URL in the browser’s address bar.
The page you’re trying to access has been removed or moved to another URL.
The server hosting the requested page is unavailable or not functioning.
Server configuration issues preventing proper request handling.

To fix the 404 error, you can try the following actions:

Check the URL for any typos in the browser’s address bar and make sure there are no mistakes.
Try refreshing the page by pressing F5 or using the “Refresh” button in the browser.
If you clicked a link from another website or page, notify the website owner about the problem so they can fix the broken link.
If you’re the website owner, make sure the requested page exists and is correctly configured on the server.
If the problem persists, the server hosting the page may be unavailable. Try accessing the page later or contact the server administrator for further assistance.

I hope this information helps you resolve the 404 error.
