Unexpected EOF or 0 bytes from the transport stream

Hello, I was trying to download a video today and an exception popped up, that I haven't seen before: (styliezed error from catch block calling $"Unknown error for url {videoUrl}\nMessage:\n{e.Message}\nStacktrace:\n{e.StackTrace}" )

Unknown error for url https://youtu.be/rIX35SBA_lQ Message: Received an unexpected EOF or 0 bytes from the transport stream. Stacktrace: at System.Net.Security.SslStream.FillBufferAsync[TIOAdapter](TIOAdapter adapter, Int32 numBytesRequired) at System.Net.Security.SslStream.ReadAsyncInternal[TIOAdapter](TIOAdapter adapter, Memory1 buffer) at System.Net.Http.HttpConnection.ReadAsync(Memory1 destination) at System.Net.Http.HttpConnection.ContentLengthReadStream.ReadAsync(Memory1 buffer, CancellationToken cancellationToken) at YTDownloader.Program.Download(YouTubeVideo stream, String fileName, Boolean masterProgressBarPresent) in C:\Users\mnagy\Projects\C#\YTDownloader\YTDownloader\Program.cs:line 644 at YTDownloader.Program.DownloadProgressiveVideo(IList1 streams, Boolean masterProgressBarPresent) in C:\Users\mnagy\Projects\C#\YTDownloader\YTDownloader\Program.cs:line 544 at YTDownloader.Program.DownloadVideo(IList1 streams, Arguments parsedArgs, Boolean masterProgressBarPresent) in C:\Users\mnagy\Projects\C#\YTDownloader\YTDownloader\Program.cs:line 466 at YTDownloader.Program.HandleDownload(IList1 streams, Arguments parsedArgs, String videoUrl, ProgressBar progressBar) in C:\Users\mnagy\Projects\C#\YTDownloader\YTDownloader\Program.cs:line 195

I am downloading the stream using buffer byte[] buffer = new byte[bufferSize]; using ( var YTStream = await stream.StreamAsync() ) using ( var outFileStream = System.IO.File.OpenWrite(fileName)) { int bytesRead; while ( (bytesRead = await YTStream.ReadAsync(buffer, 0, bufferSize)) > 0) { await outFileStream.WriteAsync(buffer, 0, bytesRead); }
}

I am downloading 720p video with audio. Other videos like https://youtu.be/l06QZx2zwZI download just fine. Do you have an ideas what might be the problem?

P.S.: Sorry for the poor formatting of the code, I haven't yet properly learnt how to use markdown with code.

It works now without any changes. Seems like the problem was on Youtube's side.
