Hi there...

Just simple JS file like this

const http = require('http');
const hostname = '194.233.77.86';
const port = 4000;
const server = http.createServer((req, res) => {
res.statusCode = 200;
 res.setHeader('Content-Type', 'text/plain');
 res.end('This is a test from nodjs app.js!\n');
});
server.listen(port, hostname, () => {
 console.log(`Server running at http://${hostname}:${port}/`);
});

and run this file with PM2 Manager in aa panel, but it's show error log like here

aaPanel_Kern it's show message all ready in use.

2022-08-23T15:17:39: Port 3000 is already in use
2022-08-23T15:17:40: Port 3000 is already in use
2022-08-23T15:17:41: Port 3000 is already in use
2022-08-23T15:17:43: Port 3000 is already in use
2022-08-23T15:17:44: Port 3000 is already in use

before that, i'm using 3000 port for gitea, but gitea has been terminated and clean. now i'm using for -nodejs.. it's mean port 3000 is used by others?

aaPanel_Kern its just 1 line

tcp6       0      0 :::3000                 :::*                    LISTEN      896/httpd  

it's normal

aaPanel_Kern so what must ido? i add it port from sys-firewal application store, it's make problem thats port?
