Display a page without log in laravel

I have a page that is supposed to be visible regardless of user log in. I've tried using $this->middleware('auth')->except('getStats') but it didn't work. I tried to pass url in Handler.php where it redirects unauthenticated users to login page, but it didn't work. Any suggestion would be appreciated as I've tried a lot of things but couldn't make it work.

Handler.php :

protected function unauthenticated($request, AuthenticationException $exception)  {
    if ($request->expectsJson()) {
        return response()->json(['error' => 'Unauthenticated.'], 401);
    }
    return redirect()->guest(route('login'));
}

PlanningController.php (where I passed the except):

public function __construct() {
    parent::__construct();
    $this->middleware('auth')->except('getStats');
}

RedirectIfAuthenticated.php

public function handle(Request $request, Closure $next, $guard = null)
    {
      // Teste si l'utilisateur est ok
      if (Auth::guard($guard)->check()) {
        // Redirige vers l'accueil
        return redirect('/');
      }
      return $next($request);
    }
