Hi @usmailaabdoul! Would you mind sharing your server.js? I'm guessing without knowing the contents of your server.js, but do you have app.listen instead of server.listen? as server = http.createServer is the instance that is initialised with the socketio library

const express = require('express');
const socketio = require('socket.io');

const formatMessage = require('./utils/messages');
const constants = require('./utils/constants');

const app = express();
const server = http.createServer(app);
const io = socketio(server);

server.listen(PORT, () => console.log(`Server running on port ${PORT}`));

Hello @JBrLloyd Thanks for your response i actually used app.listen instead of server.listen, been used to using to app.listen so couldn't see it to be the mistake, changing it fixed the problem thanks so much for your help 😊
