Question

我正在尝试在我自己的服务器上设置演示hello world alexa技能（A raspberry pi）。我在Mac上试过这个并且它可以工作。

我正在遵循这些说明：https://developer.amazon.com/public/solutions/alexa/alexa-skills-kit/docs/deploying-a-sample-skill-as-a-web-service

我们正在使用alexa-skills-kit-1.4.0.jar和非自签名的https证书。

服务器运行，我们可以使用curl从外部服务器测试它。但是，如果我从alexa网站测试，服务器会给出错误：

Error "Caused by: java.io.IOException: Connection reset by peer" with hello world java example (external server)

这是我们使用curl发送的请求有效：

curl -v https://samneaves.ddns.net:443/hello --data-binary '{

然而，当从alexa测试发送请求时，我们收到错误“无法调用远程端点，或者它返回的响应无效。”
