Owin 自我主机 SSL 连接重置
Owin self host SSL connection reset
我在为自托管 Owin 控制台应用程序设置 HTTP 时遇到问题。浏览器总是显示连接重置错误。
我已尝试根据此 link http://chavli.com/how-to-configure-owin-self-hosted-website-with-ssl/ 手动创建证书，但我仍然遇到该端口上的连接重置问题。
我检查了 windows 事件日志，没有错误消息。
应用程序将自行创建 X509 证书并自动 运行 netsh 命令。
没有Ssl，应用程序可以正确显示网页。
任何人都可以 运行 下面我的代码，看看它是否可以在您的计算机上运行？
提前致谢。
