Hi, I have checked with a non entreprise GitHub repository (to check if it was a regression) and the authentification works. It will be difficult for me to check with a GitHub repository, so maybe you can give more informations about the issue:

• if you use System Designer with a browser, could you open the console and tell me if an error is shown.
• if you use System Designer on macOS, could you open the console (View > Toggle Developer Tools) and tell me if an error is shown.

From the documentation of the lib I use (see http://github-tools.github.io/github/docs/3.2.3/GitHub.html ), I will need to expose the base Github API URL as a new configuration value.
