Symfony 4 access_control not working by roles

Question

I try to set access level on my routes and i wrote this simple security.yaml

security:
# https://symfony.com/doc/current/security.html#where-do-users-come-from-user-providers
encoders:
    App\Entity\User: bcrypt

providers:
    db_provider:
        entity:
            class: App\Entity\User
            property: mobile
firewalls:
    dev:
        pattern: ^/(_(profiler|wdt)|css|images|js)/
        security: false
    main:
        anonymous: ~
        form_login:
            login_path: verify_token_page
            check_path: verify_token_page
            default_target_path: panel_index

# Easy way to control access for large sections of your site
# Note: Only the *first* access control that matches will be used
access_control:
     - { path: ^/panel, roles: ROLE_SERVICE_MAN }

Problem is , when i try to access localhost:8000/panel , i get AccessDeniedHttpException

Here is my user role dump

array:1 [▼
  0 => "ROLE_SERVICE_MAN"
]

And i also tried to use not roles but role or wrap ROLE_SERVICE_MAN with brackets

Here is my PanelController

<?php

namespace App\Controller;

use App\Entity\Car;
use App\Entity\User;
use App\Form\CarType;
use App\Repository\CarRepository;
use App\Repository\RequestRepository;
use Symfony\Bridge\Doctrine\Form\Type\EntityType;
use Symfony\Component\Form\Extension\Core\Type\DateType;
use Symfony\Component\Form\Extension\Core\Type\TextareaType;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Routing\Annotation\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;

/**
 * @Route("/panel")
 */
class PanelController extends Controller
{
    /**
     * @return \Symfony\Component\HttpFoundation\Response
     * @Route("/",name="panel_index")
     */
    public function indexAction()
    {
        return $this->render('panel/index.html.twig');
    }

}

OK , Point 1 : i found the problem never try to change user role directly from your database because that set once when you login in cache or cookie or etc ... (i dont know where exactly) when you change you should re login or add another user to set new roles .

Point 2 : check key Roles ( and do not add Role [my mistake]) in your entity .
