Hi, my nodejs has connect ETIMEDOUT error. i wonder what is happening.

this is my connection on my nodejs var mysql = require(‘mysql’);

var con = mysql.createConnection({ host: “db-mysql-xxx-xxx-do-user-xxx-0.a.db.ondigitalocean.com”, user: “xxx”, password: ‘xxx’, database: “xxx”, multipleStatements:true, port: 8889, queryTimeout: 6000, connectTimeout: 60000, });

con.connect(function (err){ if(err) throw err; });

module.exports = con;
