firewalls doesn't work Symfony3

Question

I'm trying to configure the firewall, but I'm not rediect to login page when I go on http://localhost/project1/web/app_dev.php/

I've already used sometimes this similar configuaration on an other symfony2 project and I never meet this problem.

Maybe I forgot to do something...I done a cache:clear but no resultat after.

My security.yml:

# To get started with security, check out the documentation:
# http://symfony.com/doc/current/security.html
security:
    encoders:
        FOS\UserBundle\Model\UserInterface: bcrypt

    role_hierarchy:
        ROLE_ADMIN:       ROLE_USER
        ROLE_SUPER_ADMIN: ROLE_ADMIN

    providers:
        fos_userbundle:
            id: fos_user.user_provider.username

    # http://symfony.com/doc/current/security.html#b-configuring-how-users-are-loaded

    firewalls:
        main:
            pattern: ^/
            form_login:
                provider: fos_userbundle
                login_path: /login
                check_path: /login_check
                csrf_token_generator: security.csrf.token_manager
            logout:
                path:   /logout
                target: /
            anonymous:    ~

        # disables authentication for assets and the profiler, adapt it according to your needs
        dev:
            pattern: ^/(_(profiler|wdt)|css|images|js)/
            security: false

    access_control:

        - { path: ^/admin/, role: ROLE_ADMIN }
