Answer 1

First of all check wheather redis is running in your machine or not.
if not google it you will find.
->check these points wheather you had done correctly:
1.check wheather the data you send to sockets are in string format.
2.check the json you are sending to sockets is correctly parsed.
3.similarly check the data received from sockets is correctly parsed.
if you want to automatically reconnect to sockets use
https://github.com/joewalnes/reconnecting-websocket copy the js file there and place the script in your html and then replace WebSocket to ReconnectingWebSocket

This problem arise due to reddis channel not working at backend after configuring in the setting.py you should start the reddis channel
if you are using docker then try this
docker run -p 6379:6379 -d redis:5

if u have connections problem with django-channels,
first install channels --> pip install -U channels
after installing channels add 'channels' install app in your setting.py file and follow these docs to install channels properly in your django project

after installing django channels now install channels-redis in your django project,
first step is to install redis in your local machine , but install redis 5 or above
follow installing steps to install redis server in ubuntu and download redis direct if you use windows.

I had similar problem .
My websocket connect and disconnect immediately ,
Although Redis was installed,
The problem was with the Redis version.
Your Redis version must be greater than five
