Laravel Authentication and routing with socialite

Somebody please help me.I am trying to implement Socialite Authentication,everything works fine but routes under auth is not working.They are redirect back to login page.What is problem with my Auth or Routes.My Route and Controller files are below

Route::group(['middleware' => ['web']], function () {
Route::get('facebook',array( 
'as' => 'facebook', 
'uses' =>'FacebookController@redirectToProvider'
));
Route::get('Callback', 'FacebookController@handleProviderCallback');
}); 
Route::group(['middleware' => ['web','auth']], function () {    
Route::get('play', function () {
    return view('landing');
});

 Route::get('go', function () {
    return view('landing');
});
});

Controller

public function handleProviderCallback()
{
    try 
    {
        $user = Socialize::with('facebook')->user();
    } 
    catch (Exception $e) 
    {
        return Redirect::to('login');
    }

    $authUser = $this->findOrCreateUser($user);
    Auth::login($authUser, true);
    $user = Auth::user();
        return Redirect::to('play');       
}

    private function findOrCreateUser($facebookUser)
    {
        if ($authUser = User::where('id', $facebookUser->getId())->first()) 
        {
            return $authUser;
        }
        return User::create([
            'id' => $facebookUser->getId(),
            'name' => $facebookUser->getName(),
            'email' => $facebookUser->getEmail(),
            'gender' => $facebookUser->user['gender'],
            'avatar' => $facebookUser->getAvatar(),
            'avatar_original' => $facebookUser->avatar_original,
            'verified' => $facebookUser->user['verified']
        ]);
    }
