请教websocket-sharp的问题？

[xyzliuin]

websocket-sharp 需要配置一行：

ws.SslConfiguration.EnabledSslProtocols = System.Security.Authentication.SslProtocols.Tls12 | System.Security.Authentication.SslProtocols.Tls11 | System.Security.Authentication.SslProtocols.Tls;

在win7下正常工作，windows server 2008却不能工作，报错

握手失败，端口问题？

应该就是协议配置的问题，上面的代码在windows server2008 下，可能没有正确执行 有没有知道怎么解决的？
