Meteor google oauth - error 400

Question

I get an 400 error when I try to do any kind of authorization using oauth. I tried different browsers and different code implementations, but still failed.
So I cloned a simple app from Levelup tutorial repo on Github, and after inserting secret key from api's I'm still getting 400 error
API parameters:
