I am using socket.io and using this guide to implement it and the server is able to start up with no errors. But whenever I try connecting to the WebSocket from the server I am getting an error similar to this: Did not receive a valid HTTP response.

I am initializing socket.io with this code:

const socketio = new Server(http, {
  serveClient: false,
  pingInterval: 10000,
  pingTimeout: 5000,
});

Edit:

I am trying to connect to the WebSocket with this URL: ws://localhost:8000 using Python's WebSocket package. I used their example which is this:

import asyncio
import websockets

async def connect():
    await websockets.connect("ws://localhost:8000")

asyncio.run(connect())

Edit I made it work by using the wss package instead
