Connection to DB with socket refused in Laravel

Question

I'm aware of a ton of hits on SO and Google about this issue, still I have a unique problem it seems.

Error message: SQLSTATE[HY000] [2002] Connection refused

Configuration

    'mysql' => array(
        'driver'    => 'mysql',
        "host"      => "localhost:/var/run/mysqld4.sock",
        'port'      => '3304',
        "username"  => "admin",
        "password"  => "admin",
        "database"  => "frontend_generic",
        'charset'   => 'utf8',
        'collation' => 'utf8_unicode_ci',
        'prefix'    => 'pre_',
    ),

I confirmed that my database is running on port 3304, my prefix is correct, as are user, database and password.

For host I tried "localhost", "127.0.0.1", "http://127.0.0.1" and even the actual ip-address of the server.

Still, there is no luck or change. I tried using the exact same configuration in the local database.php file, but as expected, nothing changes.

Out of options, what am I missing here?

Update:

This is code from another app that works with this configuration. This is Kohana, not Laravel, but it works.

 "general" => array
        (
            "type"       => "mysql",
            "connection" => array
            (
                "hostname"   => "localhost:/var/run/mysqld4.sock",
                "username"   => "admin",
                "password"   => "admin",
                "persistent" => FALSE,
                "database"   => "frontend_generic",
            ),
            "table_prefix" => "pre_",
            "charset"      => "utf8",
            "caching"      => FALSE,
            "profiling"    => TRUE,
        ),

When using sockets with laravel 5, use the unix_socket config instead of host and port.

While changing to IP addresses does work, there can be advantages to using sockets when the database server is on the same machine.

Correcting the configuration originally posted:

    'mysql' => array(
        'driver'           => 'mysql',
        "unix_socket"      => "/var/run/mysqld4.sock",
        "username"         => "admin",
        "password"         => "admin",
        "database"         => "frontend_generic",
        'charset'          => 'utf8',
        'collation'        => 'utf8_unicode_ci',
        'prefix'           => 'pre_',
    ),
