我的代码上周正在运行，并且刚刚开始在周末失败。不幸的是它来自一个库https://github.com/canton7/RestEase/所以我很难调试正在发生的事情。我这里有网络跟踪日志。

突出的一点是“剩下0个客户证书可供选择”。我认为这是密钥证书错误，但我该如何解决？我没有添加任何证书或做任何事情来使它最初工作。代码基本上是https://github.com/canton7/RestEase/

中的简单示例

1 个答案:

答案 0 :(得分：0)

我修正了这个问题：https://github.com/canton7/RestEase/issues/45

  

我想我已经找到了。我正在使用传统的控制台应用程序。虽然它   已经设置编译为4.5很长一段时间它看起来像   默认SSL设置是遗留的。我通过使用它来实现它   System.Net.ServicePointManager.SecurityProtocol | =   SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12;
