NodeJS only listens on localhost

I have developed a NestJS Server application. NestJs is a node server running with express written in TypeScript.

Now I want to deploy the application on my rapsberry pi. However, I'm only able to access the server from localhost. If I try to access from a different client no content is returned. (The "^C" in the picture is only the cancel sign ;D)

I already set the hostname to 0.0.0.0. What else can I do?

# /src/main.ts 
import {NestFactory} from '@nestjs/core';
import {AppModule} from './app.module';

async function bootstrap() {
  const app = await NestFactory.create(AppModule);
  app.enableCors();
  await app.listen(3001, '0.0.0.0');
}

See picture

const express = require('express');
const app = express();
const port = 3000; // Choose your desired port

app.get('/', (req, res) => {
  res.send('Hello, World!');
});

// Change from 'localhost' to '0.0.0.0'
app.listen(port, '0.0.0.0', () => {
  console.log(`Server is listening on port ${port}`);
});

You must open firewall port and service, see below (this works for CentOS box):

#add port
sudo firewall-cmd --add-port=3001/tcp  --permanent

# add service
sudo firewall-cmd --permanent --add-service=http

# reload !!! IMPORTANT !!!
sudo firewall-cmd --reload
