Web服务器在充当网关或代理服务器时收到无效响应

当尝试使用Google .net客户端库的服务帐户将web应用程序部署到Azure时，它返回以下错误

502 - Web服务器在作为网关或代理服务器。

代码示例:

var certificate = new X509Certificate2(KeyFilePath, "notasecret", X509KeyStorageFlags.Exportable);
ServiceAccountCredential credential = new ServiceAccountCredential(
    new ServiceAccountCredential.Initializer(serviceAccountEmail) {
                        Scopes =  new string[] { AnalyticsService.Scope.Analytics };
                    }.FromCertificate(certificate));
// Create the service.
AnalyticsService service = new AnalyticsService(new BaseClientService.Initializer()
                {
                    HttpClientInitializer = credential,
                    ApplicationName = "Analytics API Sample",
                });

上面的代码在开发中运行时可以工作。然而，当部署到AZURE时，它返回一个错误。

var certificate = new X509Certificate2(KeyFilePath, "notasecret", X509KeyStorageFlags.Exportable);

var certificate = new X509Certificate2(KeyFilePath, "notasecret", X509KeyStorageFlags.MachineKeySet | X509KeyStorageFlags.Exportable);
