设置alexa服务器Hello World演示

Question

I am trying to set up the demo hello world alexa skill on my own server (A raspberry pi). I have tried this on a mac and it works.

I am following these instructions : https://developer.amazon.com/public/solutions/alexa/alexa-skills-kit/docs/deploying-a-sample-skill-as-a-web-service

We are using alexa-skills-kit-1.4.0.jar, and a non-self signed https certificate.

The server runs, and we can test it using curl, from an external server. However if I test from the alexa website the server gives the error:

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

This is the request we are sending with curl which works:

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

However, when sending a request from the alexa test we get the error "The remote endpoint could not be called, or the response it returned was invalid."

And the log output on the server is:

You will need to set up SSL with a certificate trusted by Amazon. Read https://developer.amazon.com/public/solutions/alexa/alexa-skills-kit/docs/developing-an-alexa-skill-as-a-web-service#requirements-for-your-web-service for requirements of your skill end point.
