Fix an HTTP 404 Not Found error code by refreshing the webpage giving the error, correcting the URL if typed incorrectly, moving up a directory level, clearing the browser's cache or changing the computer's DNS server. It may also be helpful to close the webpage and try to locate it independently through a search engine. If none of these solutions work, contact the website to report the error and determine if the problem is on the client side.
A 404 error indicates that the webpage can't be found on the client's server. Common messages displayed for this problem include "404 Error," "404 Not Found," "The requested URL was not found on this server," "404 File or Directory Not Found" and "404 Page Not Found."
If receiving a 404 error for a whole website, check to see if the website is accessible on another computer or device, such as a mobile phone or tablet. If so, change the DNS server on the computer. It is possible the website is being filtered or censored, or there is some other problem with the server.
A website may move a page or resource without redirecting the old URL to the new location. This can result in a 404 error.
