What am I doing wrong or where does the error come from? Yesterday everything worked well..

My web.php

Route::get('/', function () {
return view('welcome');
})->name('home');

Route::post('/signup', [
  'uses' => 'UserController@postSignUp', 
  'as' => 'signup' 
]);

Route::post('/signin', [ 
  'uses' => 'UserController@postSignIn', 
  'as' => 'signin' 
]);

Route::get('/dashboard', [
  'uses' => 'UserController@getDashboard',
  'as' => 'dashboard',
  'middleware' => 'auth'  
]);

My UserController.php :

use App\User;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;

class UserController extends Controller{


public function getDashboard(){
  return view('dashboard');
}

public function postSignUp(Request $request){

  $this->validate($request, [
    'email' => 'required|email|unique:users',
    'name' => 'required|max:120',
    'password' => 'required|min:4'
  ]);

  $email = $request['email'];
  $name = $request['name'];
  $password = bcrypt($request['password']); 

  // Create a user
  $user = new User();

  $user->email = $email;
  $user->name = $name;
  $user->password = $password;

  $user->save();

  Auth::login($user); // Pass the created user for auto login

  return redirect()->route('dashboard');

}

public function postSignIn(Request $request){

  $this->validate($request, [
    'email' => 'required|email',
    'password' => 'required'
  ]); 

  if (Auth::attempt(['email' => $request['email'], 'password' => $request['password']])) {
      return redirect()->route('dashboard');
  }
  return redirect()->back();
}

}

My User.php :

<?php

namespace App;

use Illuminate\Contracts\Auth\Authenticatable;
use Illuminate\Database\Eloquent\Model;

class User extends Model implements Authenticatable
{
    use \Illuminate\Auth\Authenticatable;
}

My RedirectIfAuthenticated.php :

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Support\Facades\Auth;

class RedirectIfAuthenticated
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @param  string|null  $guard
     * @return mixed
     */
    public function handle($request, Closure $next, $guard = null)
    {
        if (Auth::guard($guard)->check()) {
            return redirect()->route('home');
        }

        return $next($request);
    }
}

php artisan route:list outputs this:

I use XMAPP and publish the application on localhost:81 because port 80 was already taken.

Hope you can help me..

I don't see any routes that might trigger this. Only thing is that non auth users trying to reach your dashboard would be redirected to /login which might cause this trigger. Make the following changes. You're also missing guest middleware to redirect users who are already logged in.

Redirect unauthenticated users trying to access auth pages.

app/Exceptions/Handler.php

return redirect()->guest(route('home'));

You need to redirect auth users trying to access guest only page, so redirect them to dashboard and not home.

app/Http/Middleware/RedirectIfAuthenticated.php

return redirect()->route('dashboard');

Apply guest middleware to non-auth routes.

<?php

Route::group(['middleware' => ['guest']], function () {

    Route::get('/', function () {
        return view('welcome');
    })->name('home');

    Route::post('signup', [
        'uses' => 'UserController@postSignUp',
        'as' => 'signup'
    ]);

    Route::post('signin', [
        'uses' => 'UserController@postSignIn',
        'as' => 'signin'
    ]);
});


Route::get('dashboard', [
    'uses' => 'UserController@getDashboard',
    'as' => 'dashboard',
    'middleware' => 'auth'
]);
