Express not catching request to '/'

I have a quite bizzare issue - somehow, Express does not capture my request to my root route.

My Route File looks to following:

'use strict';

var errors = require('./components/errors');
var auth = require('./controllers/auth');
var ensureLoggedIn = require('connect-ensure-login').ensureLoggedIn;
module.exports = function(app) {

  // Insert routes below

  // All undefined asset or api routes should return a 404
  app.route('/:url(api|auth|components|app|bower_components|assets)/*')
   .get(errors[404]);

  app.route('/login')
    .get(auth.login)
    .post(auth.loginUser);
  app.route('/logout')
    .get(auth.logout);
  // All other routes should redirect to the index.html
  app.route('/*')
    .get(ensureLoggedIn('/login'), function(req, res) {
      console.log("req to /");
      res.sendfile(app.get('appPath') + '/index.html');
    });

};

So what happens:

• I request '/' and it sends me directly to my root and the app runs. Except: It does not require me to login, and also the Log Output does not show that any request has been made.

• If i request '/users' (Angular Route) it redirects me to '/login', as expected and then continues on its path.

Any idea what would be causing this behavior?
