所以看起来这个问题与 Server 2008 只有 TLS 的 Server 子项的注册表项有关，而不是 SCHANNEL 上的 TLS 的 Client 子项注册设置.看图

So it looks like the issue was related to the Server 2008 only having The registry entries for the Server subkey of TLS and not the Client subkey of TLS on the SCHANNEL Reg setting. See picture

一旦我添加了客户端子密钥并启用了 TLS 1.2 加密，它终于开始工作了.

Once I added the Client Subkey and enabled TLS 1.2 Encryption, it finally started to work.
