В Laravel Homestead не работают супервизоры

Недавно я установил Horizon в проект Laravel, который работает в ящике Homestead Vagrant.

Моя проблема в том, что работники очереди не забирают задания. У меня нет кураторов:

vagrant@homestead:~/Code/project$ artisan horizon:list
+----------------+------+-------------+---------+
| Name           | PID  | Supervisors | Status  |
+----------------+------+-------------+---------+
| homestead-D2dV | 7094 | None        | running |
+----------------+------+-------------+---------+

vagrant@homestead:~/Code/project$ artisan horizon:supervisors
No supervisors are running.

Вот моя конфигурация супервизора (horizon.conf):

[program:horizon]
process_name=%(program_name)s
command=/usr/bin/php /home/vagrant/Code/project/artisan horizon
autostart=true
autorestart=true
user=vagrant
redirect_stderr=true
stdout_logfile=/home/vagrant/Code/project/storage/logs/horizon.log

Когда я включаю эту машину, мои журналы и веб-интерфейс указывают, что "Горизонт успешно стартовал.".

И моя конфигурация горизонта (Horizon.php):

'environments' => [
    'production' => [
        'supervisor-1' => [
            'connection' => 'redis',
            'queue' => ['default', 'queue-1', 'queue-2', 'queue-3'],
            'balance' => 'auto',
            'processes' => env('HORIZON_PROCESSES', 10),
            'tries' => 3,
        ],
    ],

    'local' => [
        'supervisor-1' => [
            'connection' => 'redis',
            'queue' => ['default', 'queue-1', 'queue-2', 'queue-3'],
            'balance' => 'auto',
            'processes' => env('HORIZON_PROCESSES', 3),
            'tries' => 3,
        ],
    ],
],

Мой руководитель, похоже, тоже активен:

Есть какие-нибудь мысли или идеи относительно того, почему мой руководитель (-ы) не работает?
