title: Django development server showing Error 61 Connection Refused with Redis
body: <p>I am trying to follow the tutorial on read the docs for Django Channels. In the <code>settings.py</code> file I am trying to change the inmemory BACKEND to the redis backend with the following code:</p>
  
  <pre><code>CHANNEL_LAYERS = {
      "default": {
          "BACKEND": "asgi_redis.RedisChannelLayer",
          "CONFIG": {
              "hosts": [("localhost", 6379)],
          },
          "ROUTING": "chan.routing.channel_routing",
      },
  }
  </code></pre>
  
  <p>However, the moment I do this, the console which is running the <code>runserver</code> command shows the following error:</p>
  
  <pre><code>ConnectionError: Error 61 connecting to localhost:6379. Connection refused.
  </code></pre>
  
  <p>How can I fix this?</p>
