When using the header function to send a request, if a 404 failure is returned, it may be caused by the resource not existing, URL address case error, server configuration error, redirection problem, or network connection problem. By checking the correctness of the URL address, server configuration, redirection settings, network connection, etc., you can solve the problem of header function returning 404 failure.
