Question

Encountering a Error in Django Channels: WebSocket Connection Unsuccessful

I encountered an issue with the WebSocket connection to 'ws://127.0.0.1:8000/room/ws/tech' failing. I am currently exploring how to develop a real-time Django application using channels and referring to this informative tutorial.

During my attempt to establish a websocket, the console displayed the following error :

WebSocket connection to 'ws://127.0.0.1:8000/ws/tech/' failed

This is the code snippet where I am trying to create the websocket -

console.log("roomname: "+roomName);
    const chatSocket = new WebSocket(
        'ws://'
        + window.location.host
        + '/ws/'
        + roomName
        + '/'
    );

I can confirm that the URL is being constructed correctly. Even when manually entering 'ws://127.0.0.1:8000/room/ws/tech' in a browser console, it still throws the same error.
