When I tried logging in from my Google account. Every time It direct me to a nextPage.html and redirect me back to the index page. This is not allowing me to use the application.

Start by reproducing the Google-account login flow described in the issue and inspect the transition through nextPage.html and back to the index page. Trace where the redirect loop begins; done means a Google login reaches the application instead of returning to the index page.
