Laravel 5.3 Socialite facebook login

I followed this http://ift.tt/2eXXkAl tutorial on how to use laravel socialite, although i am using laravel 5.3, the syntax still works fine for me.

---

Problem

The problem is that when i click my fb login link, which refers to my callback function in my AuthController. I get stuck on the callback link with a url lke this localhost:8000/callback?code=<very long code here>, and then when i try to refresh the browser, it gives me this error InvalidStateException in AbstractProvider.php line 200.

---

Code

This is the callback function

 public function handleProviderCallback()
    {
        $user = Socialite::driver('facebook')->user();
    }

Redirect function

public function redirectToProvider()
    {
        return Socialite::driver('facebook')->redirect();
    }

My routes

Route::get('/', function () {
    return view('welcome');
});

Auth::routes();

Route::get('/home', 'HomeController@index');
Route::get('/redirect', 'Auth\AuthController@redirectToProvider');
Route::get('/callback', 'Auth\AuthController@handleProviderCallback');

Notes

Before this error happened, i have already made the facebook pop-up work but then i got the cacert.pem error. But i already fixed that by downloading the cacert.pem and configuring php.ini.

Things i've tried

I tried using dd on the $user and the output is this:

User {#192 ▼
  +token: "EAAEjWyWCELYBANza7O7zUIWqYyxG6nZBO8EcuTLCxIeyJ9qP3bcpgrVVxyQpqbTAIHx7ZA69UDs56pWQUca3ZBo7FUSt9cV4kWkhxw3KqbhDJGesB4gvOK95XYQ4QGuRZBABNRNztGrWwD5bZAB2ZApIhIiiHbiW0ZD"

  +user: array:6 [▶]
  +"avatar_original": "http://ift.tt/2eXSCTg"
  +"profileUrl": "http://ift.tt/2eG9pM5"
}

I replaced my name and email there.
Any help would be much appreciated!
