Error: connect ECONNREFUSED 127.0.0.1:465 nodemailer

I was using my gmail account to send an smtp alert messages to my users email . Example, registration or account blocked etc. I am using a nodemailer and was email were sent successfully without a single failure. Below is my code .

var nodemailer = require("nodemailer");

// create reusable transport method (opens pool of SMTP connections)
var smtpTransport = nodemailer.createTransport("SMTP",{
    service: "Gmail",
    auth: {
        user: "gmail.user@gmail.com",
        pass: "userpass"
    }
});

// setup e-mail data with unicode symbols
var mailOptions = {
    from: "Fred Foo ✔ <foo@blurdybloop.com>", // sender address
    to: "bar@blurdybloop.com, baz@blurdybloop.com", // list of receivers
    subject: "Hello ✔", // Subject line
    text: "Hello world ✔", // plaintext body
    html: "<b>Hello world ✔</b>" // html body
}

// send mail with defined transport object
smtpTransport.sendMail(mailOptions, function(error, response){
    if(error){
        console.log(error);
    }else{
        console.log("Message sent: " + response.message);
    }

    // if you don't want to use this transport object anymore, uncomment following line
    //smtpTransport.close(); // shut down the connection pool, no more messages
});

Just yesterday , signup for google for business account to my @mydomain account, then replace gmail with my new google for business email that is

var smtpTransport = nodemailer.createTransport("SMTP",{
    service: "Gmail",
    auth: {
        user: "user@mydomain.com",
        pass: "userpass"
    }
});

The problem is, it does not send the email with new account. It rather returned the titled error on my console. I tried change the security of my new account to allow less secure apps from the google console all to no avail. Please what does this error implies? Also considering the user name and pwd for my email are used, is that the best option ? Please how is best achieved ? Any help would be appreciated.

Solution

Thank you for your time guys. Below is what works for me .

nodemailer.createTransport('smtps://user%myDomain.com:pass@smtp.gmail.com');

changed to

var smtpConfig = {
    host: 'smtp.gmail.com',
    port: 465,
    secure: true, // use SSL
    auth: {
        user: 'user@myDomain.com',
        pass: 'pass@pass'
    }
};
var transporter = nodemailer.createTransport(smtpConfig);

I Found the example above on the doc https://github.com/nodemailer/nodemailer . I am suspecting this may happened to you if your password contained @ symbol considering u and the smtps link. Its therefore advisable to split it into an object without the @ symbol interfering with your smtps url. This is my guess thought. Nonetheless the above solution works for me. Plus don't forget to allow less secure apps from your google console.
