error di vps + install node.js

[mzayn]

salam, baharu saya follow install whatapp-api-tutorial tapi buka link error :

(failed)net::ERR_CONNECTION_TIMED_OUT

di status index.js:83 GET /:8000/socket.io/?EIO=3&transport=polling&t=NUog27E net::ERR_CONNECTION_TIMED_OUT

install di VPS + Node.js + apanel port 8000 - done create at firewall

kenapa ya.

[ngekoding]

Apakah clientnya di domain yang sama?

[mzayn]

ya domain yang sama, tapi domain configure di cloudflare enable dns + https

-- sebelum ini bila gunanya code

var socket = io.connect(); 
errornya console : CORS 

bila buat buat baru file edit

var socket = io.connect(':8000');
    errornya : (failed)net::ERR_CONNECTION_TIMED_OUT

[ngekoding]

Sudah coba gunakan var socket = io();?

Kalau akses pakai IP bisa? Kebetulan saya belum pernah pakai Cloudflare

[ngekoding]

Saya pakai Reverse Proxy Apache bisa akses lewat domain.

[mzayn]

apache. kalau litespeed server bisa ?

ni setting di apanel saya guna.

[ngekoding]

Saya atur seperti ini

ProxyPreserveHost On
ProxyPass /myapp http://localhost:3000

Sehingga aksesnya lewat domain.com/myapp

[mzayn]

oh ya. apache.

gimana guna OLS bisa run proxy reserve ?

[mzayn]

utk code ini. bisa untuk OLS ?

const http = require('http');

const hostname = '127.0.0.1';
const port = 3000;

const server = http.createServer((req, res) => {
  res.statusCode = 200;
  res.setHeader('Content-Type', 'text/plain');
  res.end('Hello World form node js app.js\n');
});

server.listen(port, hostname, () => {
  console.log(`Server running at http://${hostname}:${port}/`);
});

source : https://openlitespeed.org/kb/running-node-js-apps-with-openlitespeed/

gimana mau setting di app.js ?

[mzayn]

Saya atur seperti ini

ProxyPreserveHost On
ProxyPass /myapp http://localhost:3000

Sehingga aksesnya lewat domain.com/myapp

sudah solve.

....

sekarang errornya bahagian multiple device

Cannot GET /whatapp-api error.

bahagian terminal port run normally.

[ngekoding]

Mungkin salah akses URL saja.

[mzayn]

Mungkin salah akses URL saja.

selesai..

tapi bila buat run code.... qrcode di site jadi error

ini screencapturenya.

tapi di console tiada errornya.

[mzayn]

Mungkin salah akses URL saja.

gimana mau kurangkan load server untuk running app.js limit untuk scan qr cuma 3 - 5 kali retry sahaja ya?

perlu setting di reverse proxy atau buat code yang baru.
