Laravel 5.5 administrator route issue - laravel

Question

I have the below mentioned route:
Route::get('/', 'HomeController#index');
Route::get('administrator', array('before' => 'auth', 'uses' => 'Administrator\IndexController#index'));
//Route::get('/administrator', 'Administrator\IndexController#index');
Route::group(['prefix' => 'administrator'], function() {
Route::get('login', 'Administrator\IndexController#index')->name('login');
Route::post('login', 'Auth\LoginController#doLogin');
Route::get('logout', 'Auth\LoginController#logout');
});
My intention is when someone try to access http://127.0.0.1:8000/administrator/ this will go directly to the login page of the administrator.
However, when I tried to access the same, it said 404 not found.
IndexController under Administrator folder is looks below:
class IndexController extends Controller {
/**
* Create a new controller instance.
*
* #return void
*/
public function __construct() {
$this->middleware('guest')->except('doLogout');
}
public function index() {
//$session = session()->all();
if(Auth::check() == 1){
return Redirect::intended('/administrator/dashboard')->with('successMessage', 'You have successfully logged in.');
}
//print_r($session);
//echo $session['_token'];
//if($session['_token'] == '')
$data = array();
$data['title'] = "Shop To My Door - Administrator Panel";
return view('Administrator.index.index', $data);
}
}

Answer 1

You have route and group with the same name "administrator"
My suggestion for routing:
Route::get('/', 'HomeController#index');
Route::group(['prefix' => 'administrator'], function() {
Route::get('/', 'Administrator\IndexController#index');
Route::get('login', 'Administrator\IndexController#login');
Route::post('login', 'Auth\LoginController#doLogin');
Route::get('logout', 'Auth\LoginController#logout');
});
