AppBuilder: Problem using HTTPs for a OData Data Source

Hi,

I'm having trouble creating a HTTPS-based OData Data Source.

I installed AppBuilder based on the installation instructions.

I'm not behind a corporate firewall.

I'm getting a node.js error:

[2014-02-09 11:37:17.175] [INFO] AB - CANNOT resloved: https

[2014-02-09 11:37:18.153] [INFO] AB - An error occured: connect ECONNREFUSED

[2014-02-09 11:37:18.154] [ERROR] AB - 127.0.0.1 - - "GET /proxy/https%3A%2F%2F7jg.europe.sap-river.com%2Fsap%2Fhana%2Frdl%2Fodata%2Fv1%2FRHIRSCH2_MyFirstRiverA

HTTP-based OData calls work fine. For example, I can create a OData Data Source based on "http://services.odata.org/NorthWind/NorthWind.svc"

I assume that I need to change some node.js configuration but I have no idea which one.

Any help would be greatly appreciated.

Thanks,

Dick
