HOW can i solve the Error: connect ETIMEDOUT when try to connect node with DO Mysql database

const MYSQL_CONF = {
    host: 'db-mysql-v1-29254-do-user-7904424-0.a.db.ondigitalocean.com',
    username: 'doadmin',
    password: 'xxxxxxxx',
    database: 'defaultdb',
    // port: 25060,
    dialect: 'mysql',
    dialectOptions: {
        ssl: {
            ssl: true,
            cert: fs.readFileSync(path.resolve(__dirname, 'ca-certificate.crt')).toString('utf8')
        }
    }
}

const con = mysql.createConnection(MYSQL_CONF)
con.connect((err, result) => {
    if (err) {
        throw new Error(err)
        return
    }
});

The configuration is coded above, and i am not sure if this is the correct one…The error always states the Error: connect ETIMEDOUT…

the funny thing is that i can connect the cluster with mysql client terminal and workbench on my local machine, but it doesn’t work with node.js…

Could someone help me out, many thanks?
