Since you double-posted, I will reply to the other thread.

I have nginx, uwsgi and asgi setup correctly. With my javascript frontend, it is connected to base on the worker log that contains the demultiplexer response. However, when I try to create a model (via API, admin or shell) it does not send a message to the worker. In `runserver` all work fine.

So I try creating the model in python manage.py shell.

$ python manage.py shell

I not really sure what I did wrong or is it a bug with Django Channels. There is no logs message about binding message being send out by the worker even when I do it successfully in the shell. 

Somehow, I find out that after I try to send a Group message to any group, creating the Feed again will sends out the message correctly.

The following is my code for connecting to redis:

CHANNEL_LAYERS = {
	"default": {
	"BACKEND": "asgi_redis.RedisChannelLayer",
	"CONFIG": {
	"hosts": [os.environ.get('REDIS_URL', 'redis://localhost:6379')],
	},
	"ROUTING": "github_hook.routing.channel_routing",
	},
	}

Any kind soul know what is the problem? Am I missing something that's why binding does not work in production?
