Загрузка видео не работает с YouTube API v3

    void videosInsertRequest_ProgressChanged(Google.Apis.Upload.IUploadProgress progress)
    {
        switch (progress.Status)
        {
            case UploadStatus.Uploading:
                Console.WriteLine("{0} bytes sent.", progress.BytesSent);
                break;

            case UploadStatus.Failed:
                Console.WriteLine("An error prevented the upload from completing.\n{0}", progress.Exception);
                break;

    }

    void videosInsertRequest_ResponseReceived(Video video)
    {
        Console.WriteLine("Video id '{0}' was successfully uploaded.", video.Id);
    }

Но я получаю progress.Status сбой каждый раз. Я не могу загрузить видео на youtube. Размер моего видеофайла - 2 МБ. Я создаю клиентский и секретный ключ для веб-приложения на странице https://console.developers.google.com. Может ли кто-нибудь помочь мне решить это, пожалуйста.

заранее спасибо
