Can someone test my github project?

I have been working on this boilerplate for a while, and the master branch works fine. However I started a feature branch for socialite integration, and I'm having issues locally. Trying to see if its just my localhost or my code. The branch is here: https://github.com/rappasoft/laravel-5-boilerplate/tree/feature/socialite_integration

The bug i'm getting on localhost is after hitting 'Authorize application' on github, I get a redirect loop on github.

I would appreciate it if anyone had the time to help.
