Unable to connect to google cloud sql service using node.js - mysql

Question

I am trying to connect to my google-cloud-sql instance using my node.js mysql module and I am unable to connect to it. I referred to the following links mysql docs and google getting started but could not understand what's going on.
var connection = mysql.createConnection({
acquireTimeout: 30000,
host : '35.184.77.86',
user : 'XXX',
password : 'XXX',
database : 'name',
});
connection.connect(function(err){
if (err) {
console.error(chalk.red('error connecting: ' + err.stack));
return;
}
console.log(chalk.green('connected as id ' + connection.threadId));
});
connection.query('SELECT * FROM likes', function(err, rows, fields)
{
if (err) {
console.log(chalk.red(err));
}else{
console.log(fields);
}
});
connection.end();
I am getting the following error while connecting.
error connecting: Error: connect ETIMEDOUT

Answer 1

Try running with the below code also check the connection and for the right IP. There might be internal firewall block between the server and the system
con.connect(function(err) {
if (err) throw err;
console.log("Connected!");
});
