我创建了示例Asp.net应用程序以获取所有日历并在日历中添加事件。我使用Visual Studio运行它时应用程序工作正常它成功加载页面，显示所有日历信息，在日历中添加事件。但是，当我在IIS上部署应用程序时，页面永远不会加载，它会使＆＃34;请求超时＆＃34; exception.Kindly help

以下是代码

private CalendarService InitGoogleService()
{
UserCredential credential;
string path = Server.MapPath("~") + @"\GCSc.json";
string credPath = Server.MapPath("~") + @"\Calendar_Data";
credential = GoogleWebAuthorizationBroker.AuthorizeAsync(new ClientSecrets
{
ClientId = "My Client Id",`enter code here`
ClientSecret = "My Client Secret"
}, Scopes, "user", CancellationToken.None, new Google.Apis.Util.Store.FileDataStore(credPath)).Result;

    CalendarService service = new CalendarService(new BaseClientService.Initializer()
    {
        HttpClientInitializer = credential,
        ApplicationName = ApplicationName,
    });
    return service;
}
