body: <p>I am trying to deploy my app using Nodejs, MySQL with sequelize as ORM on railway platform. But I saw this error:
  ConnectionError [SequelizeConnectionError]: connect ETIMEDOUT

  my database config like this:</p>
  <pre><code>const Sequelize = require('sequelize');
  const path = require('path');
  require('dotenv').config({path: path.join(__dirname, '../','.env')});
  
  const sequelize = new Sequelize(process.env.DB_DATABASE, process.env.DB_USER, process.env.DB_PASS, {
      dialect: 'mysql',
      host: process.env.DB_HOST,
      port: process.env.DB_POST,
  }, {
      define: {
         freezeTableName: true, 
      }
  });
  module.exports = sequelize;
  </code></pre>
