How to set up socket.io on App Platform

I have a Node Js app with a React Frontend deployed as an App. Unfortunately Im having a hard time making socket.io work outside of localhost… Im using ${APP_URL}/node as a route for backend and it is running on port 80.

const app = express();
const server = http.createServer(app); 
export const io = new Server(server, {
  cors: {
    origin: allowedOrigins,
    methods: ['GET', 'POST'],
  },
});
// Listen for when the client connects via socket.io-client
io.on('connection', socket);
const connectServer = async () => {
  app.set("view engine", "ejs");
  app.use(cookieParser());
  app.use(credentials);
  app.use(cors(corsOptions));
  app.use( express.urlencoded({limit: '50mb', extended: true }));
  app.use((req, res, next) => {
    if (req.originalUrl === '/stripeHook') {
      next();
    } else {
      express.json({ limit: '50mb' })(req, res, next);
    }
  });
  app.use(express.static('static'))

  const PORT = process.env.PORT || 80;
  server.listen(PORT, () =>  console.log(`Server is running on port ${PORT}.`));
}; 
connectServer();

And on client side Im using a hook

  const BASE_URL = process.env.REACT_APP_SOCKET_URL;
  socket = io(BASE_URL);
  if(userId)socket.emit("live", userId)

Im getting POLLING 200 response in my network tab but the response is ‘You need to enable javascript’.

Can someone help me out! Appreciate any help
