Error: connect ETIMEDOUT, how to solve it? using Node.js and MySQL2

Question

I used Node.js and MySQL2. Working on MySQL workbench. Created virtual DB using Railway workbench. Schemas and tables are created. But showing `ETIMEDOUT error in the VS code's terminal when i try to run node index.js. What can i do?

db.js:

import mysql2 from 'mysql2';
    
export const db = mysql2.createConnection({
    host: 'containers-us-west-174.railway.app',
    user: 'user',
    password: 'password',
    database: 'railway'
})

index.js:

import express from 'express';
import authRoutes from './routes/auth.js';
import userRoutes from './routes/users.js';
import postRoutes from './routes/posts.js';
import dotenv from 'dotenv';
import cookieParser from 'cookie-parser';
import multer from 'multer';

dotenv.config();

const app = express();

app.use(express.json());
app.use(cookieParser());


const storage = multer.diskStorage({
    destination: function (req, file, cb) {
        cb(null, '../client/public/upload');
    },
    filename: function (req, file, cb) {
        cb(null, Date.now() + '-' + file.originalname);
    }
})

const upload = multer({ storage: storage })

app.post('/api/upload', upload.single('file'), function (req, res) {
    const file = req.file;
    res.status(200).json(file?.filename)
});


app.use('/api/auth', authRoutes);
app.use('/api/users', userRoutes);
app.use('/api/posts', postRoutes);


app.listen(8800, () => {
    console.log('Connected wih backend!');
})

In my VS Code Terminal it is showing this error:

Connected wih backend!
node:events:505
      throw er; // Unhandled 'error' event
      ^

I was trying to deploting in railway. I'm using MySQL workbench.

In Railway deployment logs this error shows:

return process.dlopen(module, path.toNamespacedPath(filename));
^

}
npm WARN config production Use `--omit=dev` instead.

And deployment crashed!

Any solution?
