Websocket, an existing connection was forcibly closed by the remote host. django-channels

[Mike Johnson Jr]

So I'm getting the error as described in the title of this post.

I'm following this tutorial: https://gearheart.io/blog/creating-a-chat-with-django-channels/

Here's the full traceback:

In [1]: import websocket

In [2]: ws = websocket.WebSocket()

I have redis running, manage.py runserver running, and I'm using django-channels. This is my first time working with websockets. Can anyone help out and let me know what's wrong?

python django websocket redis django-channels

I would need to see the full console output of the server, and a full package version listing of what you have installed to help you further.
