Django Channels channels_redis not connecting

[raj program]

I'm using Django Channels in my app to make a person to person chat function. For this I'm using Django Channels channel layers that uses 'Redis' as a backing store.

I have following configuration in the settings.py:

CHANNEL_LAYERS = { "default": 

 { "BACKEND": "channels_redis.core.RedisChannelLayer", 

  "CONFIG": { "hosts": [os.environ.get('REDIS_URL', ("localhost", 6379))], }, }, }

The CHANNEL_LAYERS is working fine for development when 'hosts' points to localhost. However for production, when I'm trying to make sure that the channel layer can communicate with Redis on Heroku it does not work. Using code as giving in Channels Docs as shown below, gives the following error
