调用SSPI失败，请参阅内部异常。不支持请求的功能

Question

在我公司中，我们有一个用C＃开发的Windows服务，用于使用SSLStream和Tls12以及服务器和客户端证书来处理来自客户端的请求消息。该服务在Windows Server 2012（包括Windows 10 PC）上都运行良好，无论是以发布模式执行还是调试以检查代码，但是最近执行AuthenticateAsServer时会引发异常。一段代码是：

ServicePointManager.SecurityProtocol = SslProtocols.Tls12;
SslStream secureClient = new SslStream(networkStream, false);
secureClient.AuthenticateAsServer(serverCertificate);

networkStream是具有服务的IP和端口的NetworkStream的实例。serverCertificate是X509Certificate2，它以自签名的方式安装在本地计算机存储中。客户端具有相同的证书。异常详细信息如下：

正如我之前提到的，直到几天前，服务一直工作良好。任何帮助将不胜感激。
