Hi,

just tried your plugin on jenkins with our internal enterprise github. This is only accessible via http (not https). The code to access the api always adds the "https://api" prefix in front of it.

Github-api plugin: 1.28
Oauth plugin: 0.12

If I have time I'll try to find a workaround... Maybe someone knows quickly how this could be fixed :-)

Btw, the stacktrace says "plain" connection because I've entered the URL to github in jenkins to be http://github.internal.net:80

Stack trace is attached,
