Your web browser reports a file not found problem. The user (if they mistyped the URL, for example) or the website’s publisher can both be to blame for a 404 error message. This can happen when a web page is erased and no longer exists, also known as a broken link. Create a redirect to take the user to the updated location of the page to avoid these problems. Setting up an uniform error 404 page for your domain can help your users have a better experience, especially if you include a search bar or a list of related material.
