  code: 'ETIMEDOUT',

my code-------

var config = require('./config')('prod');
var mysql = require('mysql');
module.exports = function() {
    var connection = mysql.createConnection({
        host               : config.DATABASE_HOST,
        user               : config.DATABASE_USER,
        password           : config.DATABASE_PASS,
        database           : config.DATABASE_NAME,
        multipleStatements : true
    });
    connection.connect(function(err) {
        if (!err) {
            console.log("mysql connected")
        } else {
            console.log("mysql connection lost");
        }
    });
    return connection;
} 

The db is hosted into a remote server and the DATABASE_USER has all the permission it needed. thanks in advance .

Hi @cashFLO960 the error Error: connect ETIMEDOUT is from the Node.js networking code. It means that a TCP connection could not be established to your MySQL server. Usually this is a networking or firewall issue.

Hi there,

When creating an RDS instance via the AWS web console and when following “default” settings, AWS puts your instance into a security group with inbound rules set to your machine IP. Also, everything will work when running on your local machine but will timeout when doing the same thing in Lambda.

Solution: modify the default security group inbound rules associated with your db instance.
