我一直在尝试使用SSLstream连接到服务器。我有连接的证书&所有的证书都是正确的。但不知何故，它得到了如下错误：

System.IO.IOException: Unable to write data to the transport connection: An existing connection was forcibly closed by the remote host. --->   System.Net.Sockets.SocketException: An existing connection was forcibly closed by the remote host
