Slow Download & Error: Response status does not indicate success

[nlogozzo]

I have this code to download a video

var video = await YouTube.Default.GetVideoAsync(VideoLink);
var videoBytes = await video.GetBytesAsync();

Now sometimes it works and sometimes it doesn't. No error is throw however upon break point inspection sometimes the code doesn't go past this line var videoBytes = await video.GetBytesAsync(); yet again no error is thrown. And it's not like its specific video issues cause if I go to run it again with the same video, it works no issues. The line that seems it can't get past, it eventually got past it after two/three minutes or even longer whereas for the same code for the same video run a separate time, GeBytesAsync was instant. After continually downloading videos I finally got this error (where I guess it's just taking too long and timesout):

I think this could be related to: https://github.com/Tyrrrz/YoutubeExplode/issues/573

did u use download with chunks like this ? and can you give me a sample url ?

This is how I download:

private async Task<string> DownloadVideoAsync()
{
    Status = "Downloading...";
    Progress = 3;
    var video = await YouTube.Default.GetVideoAsync(VideoLink);
    var videoBytes = await video.GetBytesAsync();
    var videoFilePath = $"{_saveFolder}/{NewFilename}{video.FileExtension}";
    await File.WriteAllBytesAsync(videoFilePath, videoBytes);
    Progress = 6;
    return videoFilePath;
}

And like I said, it happens with different videos at different points. One time the video will download normally, the next super slow. I urge you to look at the issues I linked, I believe they might explain what's going on.

use dowload with chunk. youtube sometimes reduces download speed for +10mb videos.

I'm currently working on another project but as soon as I get to this one I'll try downloading via chunks and let you know how it goes!
