apns Sharp 中的 iPhone 证书错误 对 SSPI 的调用失败

我有一个托管在 azure 中的数据服务，我从该服务向 iphone 发送通知，但在与 apns 建立连接时出现以下错误 “对 SSPI 的调用失败。收到的消息是意外的或格式错误。”我还参考了以下链接来解决相同的错误，但仍然收到错误

苹果通过 APNS Sharp 推送通知 https://stackoverflow.com/questions/3162076/apple-push-notification-with-apns-sharp/3221612#3221612 and C# iPhone 推送服务器？ https://stackoverflow.com/questions/1056083/c-iphone-push-server

                    X509CertificateCollection clientCertificateCollection = new X509CertificateCollection(new X509Certificate[1] { clientCertificate });

                    // Create an SSL stream that will close the client's stream.
                    SslStream sslStream = new SslStream(

我也在虚拟机上安装了所需的证书。我从苹果获得的 iPhone 开发者身份证书上收到的一个警告是“Windows 没有足够的信息来验证此证书”我的 iPhone 证书有问题吗？请帮助我，我被困住了

得到解决方案我刚刚将 X509Certificate 更改为 X509Certificate2 并将 X509CertificateCollection 更改为 X509Certificate2Collection
