ESP8266 not connecting to SocketIO server

[mos29]

Please help me, I donot know where I am going wrong I have provided the server and client side code everything seems to be fine, but dont know where is the problem

/////////////////////// SERVER CODE ON NODEJS /////////////////////** var PORT = process.env.PORT || 5000; var express = require('express'); var app = express(); var http = require('http'); var server = http.Server(app);

app.get('/', (req, res) => { res.send('

Hello world

'); });

server.listen(PORT, function () { console.log('listening on *:' + PORT); } );

var io = require('socket.io')(server);

io.on('connect', function (socket) {

console.log('a user connected');

socket.on('message', function (data) {
    console.log(data);
    io.emit('message', data);
});

});

Try using EIO=3 instead of EIO=4.

webSocket.begin("192.168.1.106", 5000, "/socket.io/?EIO=3");
