The 404 or Not Found error message is an HTTP standard response code indicating that the client was able to communicate with the server but either the server could not find what was requested, or it was configured not to fulfill the request and not reveal the reason why. 404 errors should not be confused with “server not found” or similar errors, in which a connection to the destination server cannot be made at all.
