Error 0xc00d36c4 when open an mp4 downloaded from an html source

I am trying to download an mp4 file of a web page via java, but when I go to save it on my device and then open it I get the error "0xc00d36c4" or the program says that the file is corrupted. This happens to me both if I open it with VLC and with any other programs like "Film & TV by Microsoft". I leave you here the code of my program.

public class Main {

    public static void main(String[] args) {
        try {
            String code = getCode("https://www.animesaturn.it/ep/Naruto-ITA-ep-2");
            URL url = new URL(getMP4Url(code));
            URLConnection connection = url.openConnection();
            //Add the Property

            ln = reader.readLine();

    }
}

Some ideas?

Remove these two lines and it will work:

connection.addRequestProperty("If-Range", "\"4046154-5ae57e25d5964\"");
connection.addRequestProperty("Range", "bytes=4784128-13303807");//13303807 1599067366709604

HTTP Range header makes servers to send only a part of a file, while you would need the entire one. If-Range is also something similar.

Without these headers your code will download a correct 20-minute video (64 megabytes).
