无法使用代理与Node.js连接

Question

I am using node.js for my chat application with https. It is working fine in all condition but the problem is with VPN.

I installed the turbo VPN into my android phone and connected to the proxy server. After this whenever I am going to connect to the chat server it fails every time and shows an error

socket.io.min.js?v=1498289112:2 
GET https://www.xxxxx.com:30002/socket.io/?u=5&pathname=%2Fdashboard&EIO=3&transport=polling&t=Lx7Tlf8 net::ERR_CONNECTION_TIMED_OUT

Here is the requested headers

Provisional headers are shown

Origin:https://www.xxxx.com
Referer:https://www.xxxxx.com/dashboard
User-Agent:Mozilla/5.0 (Linux; Android 6.0.1; MotoG3 Build/MPIS24.107-55-2-17) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/59.0.3071.125 Mobile Safari/537.36

Here is my server.js code

var socket = require("socket.io");
var express = require("express");
var http = require('https');
var fs = require("fs");
var app = express();

 var opts = {
 key : fs.readFileSync("/home/myhomedir/ssl/keys/9ca41_e1cd7_ece6805e7bdddf1ec6859d5cb27ab30f.key"),
 cert : fs.readFileSync("/home/myhomedir/ssl/certs/xxxx_9ca41_e1cd7_1529438222_b65b92c90fc0973371157d99ea679f4f.crt"),
 ca : [fs.readFileSync("gd.crt"), fs.readFileSync("g1.crt"), fs.readFileSync("g2.crt")],
 requestCert : true,
 rejectUnauthorized : false 
 };
 var server = http.createServer(opts, app);

app.set('trust proxy', true);
var server = http.createServer(app);
var io = socket.listen(server);

Looking at your header you are connecting to your site with HTTPS but I don't see you inserting your certificate in the variable opts.

Shot in the wild but try this

Add your certificate privkey and cert to the folder you keep your server.js file in

Server side:

var fs = require('fs');

var options = {
  key: fs.readFileSync('privkey.pem'),
  cert: fs.readFileSync('cert.pem')
};

var app = require('express')();
var http = require('https').Server(options, app);
var io = require('socket.io')(http);
var port = 8080;

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

Client side:

<script>
  var socket = io.connect('https://yourwebsite.com:8080', { secure:true });
</script>
