Run Django workers servers with supervisor?

I'm trying to deploy my Django application with supervisor. When I launch supervisor it starts daphne correctly, however the worker servers are not launched.

Here's a code sample of supervisor.conf (the workers block): 

[program:runworker]
command=python /home/django/environment/myproject/manage.py runworker
stopsignal=KILL
killasgroup=true

The browser waits a long time and then it shows:

 503 Service Unavailable
Worker server failed to respond within time limit.

I could also add that if I launch the processes independently (not using any process control system ) it actually works. I'm behind an Nginx reverse proxy, but I don't think that's the issue at all..

Here's the output of Supervisor:

2016-08-17 19:01:09,439 INFO supervisord started with pid 3473
2016-08-17 19:01:10,441 INFO spawned: 'runworker' with pid 3477

You have to increase time limit and increasing capacity throughput is higher than 100 messages a second

CHANNEL_LAYERS = {
        "default": {
            "BACKEND": "asgi_redis.RedisChannelLayer",
            "CONFIG": {
                "hosts": [(XXX, XXX)],
                "channel_capacity": {
                    "http.request": 200,
                    "websocket.send*": 20,
                },
            },
            "ROUTING": "XXXXXchannel_routing"
        },
    }

You probably need to set the DJANGO_SETTINGS_MODULE environment variable.
