Error 111 connecting to localhost:6379. Connection refused. Django Heroku

Question

I am able to run redis locally and everything works.

However when I deploy to heroku I get this error:

Error 111 connecting to localhost:6379. Conn         


        

Answer 1

Error 111 is thrown when the application is unable to contact Redis. I had the same problem following the Heroku Django Channels tutorial. The settings.py file should read:

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

REDISCLOUD_URL instead of REDIS_URL.

Ensure Redis is installed on the Heroku server.
