使用自定义命名空间连接到 Heroku 套接字 io 服务器的套接字 io 超时

Question

I'm trying to connect to my server located in heroku with socket io with this code, which works when the server is ran locally but, when I try to connect to the same server on herkoku it won't connect and it will give me a timeout.

I've tried setting transport to websocket on the client and it gives me websocket error on chrome and can't establish connection on firefox.

Client side code:

const io = require('socket.io-client');    
socket = io.connect('https://herokuappurl.com:23840/custom_nsp');//not works
socket = io.connect('localhost:23840/custom_nsp');//works

Server side code:

var express = require('express');
var app = express();
var http = require('http').Server(app);
var io = require('socket.io')(http);

const PORT = process.env.PORT || 8000;
var server = http.listen(PORT,function(){
   print('listening on *:' + PORT);
});
io.of('/custom_nsp').on('connection', function(socket) {
   /*socket.on events*/
}
