在Windows 2008

Question

我编写了一个POC，它将来自.nety应用程序的SNS消息发送到AWS SNS。 安装在我的Win 7笔记本电脑上时工作正常。但是，当我在Windows Server 2008上安装它时，它会给我这个错误消息。

我很确定代码很好，因为它适用于笔记本电脑安装。 这是错误，

Answer 1

自己想出这个。 所以我的.NET应用程序使用的框架3.5不支持TLS 1.2。 我将我的项目迁移到.NET 4.5并添加了一行以确保我们始终使用TLS 1.2，因为这是在狮子狗攻击之后的事实标准。

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12

这解决了我的问题。 大多数情况下，此错误必须与您的运行时或系统的安全配置相关。
