Google API Oauth2在实时网站上超时

Question

我已经实现了访问YouTube和Analytics API的实现，这在localhost上工作正常，但是当我在预生产中尝试时，请求只是超时并且验证的同意窗口甚至都没有显示出来。

这是我的YouTube身份验证码：

string[] scopes = new string[] { YouTubeService.Scope.Youtube,  // view and manage your YouTube account
                                 YouTubeService.Scope.YoutubeForceSsl,
                                 YouTubeService.Scope.Youtubepartner,
                                 YouTubeService.Scope.YoutubepartnerChannelAudit,
                                 YouTubeService.Scope.YoutubeReadonly,
                                 YouTubeService.Scope.YoutubeUpload};

try
{
    // here is where we Request the user to give us access, or use the Refresh Token that was previously stored in %AppData%
    UserCredential credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
                                    new ClientSecrets { ClientId = clientId, ClientSecret = clientSecret }
                                    , scopes
                                    , userName
                                    , CancellationToken.None
                                    , new DatabaseDataStore("Youtube")).Result;

    YouTubeService service = new YouTubeService(new YouTubeService.Initializer()
    {
        HttpClientInitializer = credential,
        ApplicationName = "Masterpiece",
    });
    return service;
}
catch (Exception ex)
{
    Console.WriteLine(ex.InnerException);
    return null;

}

我基本上有一个＆＃34; Connect＆＃34;页面上的按钮，当我点击它时，页面应该进行回发并在服务器端对Google API进行身份验证。但在预生产中，回发只会挂起，最终我收到此错误消息：
