It is a typical HTTP-standard respond code indicating that the client was able to communicate with a given server, but the server could not find what was requested. You will get this issue not strictly with MP4 or MKV formatted files, but the most possible reason is that the file has been removed from the website.

4. If an entire website is giving you a 404 error or if the website is working on other networks, change the DNS servers used by your computer.
