laravel redirect to wrong url after auth success

[KrissSachintha]

guys I need a help, I deployed a laravel app inside domain/external folder and in the laravel app index.php i changed the paths to /../external/storage etc.
when I go to the domain it will redirect me to domain/external perfectly but however after I login in the laravel app the Auth module will redirect me to domain/ instead of domain/external
how to fix it,
I already tried this inside authcontroller but won't work
protected function redirectTo()
{
return '/path';
}

overide login function.

inside login controller (app/Http/Controllers/Auth/LoginController.php)

<?php
  
namespace App\Http\Controllers\Auth;
  
use App\Http\Controllers\Controller;
use App\Providers\RouteServiceProvider;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use Illuminate\Http\Request;
use Auth;
   
class LoginController extends Controller
{
    /*
    |--------------------------------------------------------------------------
    | Login Controller
    |--------------------------------------------------------------------------
    |
    | This controller handles authenticating users for the application and
    | redirecting them to your home screen. The controller uses a trait
    | to conveniently provide its functionality to your applications.
    |
    */
  
    use AuthenticatesUsers;
  
    /**
     * Where to redirect users after login.
     *
     * @var string
     */
    protected $redirectTo = RouteServiceProvider::HOME;
   
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('guest')->except('logout');
    }
  
     /**
     * Write code on Method
     *
     * @return response()
     */
    public function login(Request $request)
    {
        $request->validate([
            'email' => 'required',
            'password' => 'required',
        ]);
     
        $credentials = $request->only('email', 'password');
        if (Auth::attempt($credentials)) {
  
            return redirect()->route('home');
        }
    
        return redirect("login")->withSuccess('Oppes! You have entered invalid credentials');
    }
}

@lkdev bro in my laravel app there is only authController regarding login, is it normal? however I solved the issue, the issue was the subdomain which I was given was inside another subdomain so the laravel app goes crazy, so what I did was created a separate subdomain in a new hosting and tried, and that worked.
