Some assets aren't load in production

Question

I'm testing my Symfony2 development at production environment but for some reason some files aren't loaded and I can't find the issue. First, see the picture below:

As you can see many files, failed to load, internal and external (coming from CDN for example). Before test my site on production I run the command assetic:dump this create the files under /web/css, /web/images and /web/js respectively. This is what I have in my security.yml:

security:
    encoders:
        FOS\UserBundle\Model\UserInterface: sha512

    role_hierarchy:
        ROLE_ADMIN:       ROLE_USER
        ROLE_SUPER_ADMIN: [ROLE_USER, ROLE_ADMIN, ROLE_ALLOWED_TO_SWITCH]

    providers:
        fos_userbundle:
            id: fos_user.user_provider.username

    firewalls:
        dev:
            pattern: ^/(_(profiler|wdt)|css|images|js)/
            security: false
        main:
            pattern: ^/
            anonymous: ~
            form_login:
                provider: fos_userbundle
                csrf_provider: form.csrf_provider
            logout:
                 path: fos_user_security_logout
                 target: /
                 invalidate_session: false
            anonymous:   true

    access_control:
        - { path: ^/login$, role: IS_AUTHENTICATED_ANONYMOUSLY }
        - { path: ^/registro, role: IS_AUTHENTICATED_ANONYMOUSLY }
        - { path: ^/register, role: IS_AUTHENTICATED_ANONYMOUSLY }
        - { path: ^/resetting, role: IS_AUTHENTICATED_ANONYMOUSLY }
        - { path: ^/, role: ROLE_USER }
        - { path: ^/admin/, role: ROLE_ADMIN }

Since I though the problem comes from firewall but I test with this rules under access_control:

        - { path: ^/web/css, role: IS_AUTHENTICATED_ANONYMOUSLY }
        - { path: ^/web/js, role: IS_AUTHENTICATED_ANONYMOUSLY }
        - { path: ^/web/images, role: IS_AUTHENTICATED_ANONYMOUSLY }

And didn't work either so I'm complete lost at this point. I have checked also the existence of the files by running the command ll /var/www/html/sunahip/web/css/

and this is the output, so files are there:

where is the issue? Where I'm failing? Did I miss something else?

Disable all Firefox extensions that parse/manipulate CSS and try again.
