Question

我正在尝试将通过Visual Studio 2015在C＃中编码的机器人发布到AWS。我安装了Amazon Cloud SDK，并且能够将bot成功发布到AWS。我使用它给出的地址（http://benbot-dev.us-west-2.elasticbeanstalk.com/）更新了bot端点。但是，当我去Microsoft Bots站点测试机器人连接时，它说无法连接到远程服务器。请帮忙。我认为这是https端点问题。但我不知道如何获得API网关端点。

此异常消息告诉您，在服务器代码中，您尝试通过52.42.245.162到达服务器，并且此服务器无法访问（更具体地说，https端口443无法访问）。此IP解析为某个AWS主机（使用nslookup命令查找此内容，请参阅enumerate）。您可以尝试ping此IP，或尝试查看端口80是否可访问（两者都不是来自我的主机）。或者您可以尝试枚举是否在该主机上打开任何其他端口（搜索google / bing以获取有关如何执行此操作的说明）。如果您无法从主机访问该端口，则Microsoft Bots站点也无法访问该端口。如果您的服务在该IP上运行，最可能的原因是您必须打开AWS上的端口才能从公共互联网访问（搜索google / bing for aws open port或aws allow ssh）

在Microsoft上发布后，Microsoft Bot上的连接错误
