Youtube API v3 return 401 when i try to upload video

Question

I use ServiceAccount uploader for youtube. I use Youtube API v3. I have simple console application, that upload video to youtube

String serviceAccountEmail = "...";

        var certificate = new X509Certificate2(@"G:\Youtube\1ffd6ea22be7c41e0852935a0f35438e4beb2e2d-privatekey.p12", "notasecret", X509KeyStorageFlags.Exportable);
        //, YouTubeService.Scope.YoutubeUpload
        ServiceAccountCredential credential = new ServiceAccountCredential(
           new ServiceAccountCredential.Initializer(serviceAccountEmail)
           {
                                  Scopes = new[] { YouTubeService.Scope.Youtube, YouTubeService.Scope.YoutubeUpload }
           }.FromCertificate(certificate));



        var youtube = new YouTubeService(new BaseClientService.Initializer()
        {
            HttpClientInitializer = credential,
        });

        var video = new Video
        {
            Snippet = new VideoSnippet
            {
                Title = "Video title",
                Description = "Video description",
                Tags = new string[] {"tag1", "tag2"},
                CategoryId = "22"
            },
            Status = new VideoStatus {PrivacyStatus = "public"}
        };

        var fileStream = new FileStream("G:\\1.mp4", FileMode.Open);

        var videosInsertRequest = youtube.Videos.Insert(video, "snippet,status", fileStream, "video/*");
        videosInsertRequest.ProgressChanged += videosInsertRequest_ProgressChanged;
        videosInsertRequest.ResponseReceived += videosInsertRequest_ResponseReceived;

        var uploadThread = new Thread(() => videosInsertRequest.Upload());
        uploadThread.Start();
        uploadThread.Join();

        Console.Read();

But this code return error: Response status code does not indicate success: 401 (Unauthorized). Help me, please

This is result by Fiddler:
