node.js - Send Email Failed Error: queryA EREFUSED smtp.gmail.com

Question

I have a question, which from yesterday I still have not found a solution. I got an error sending an email.

The error:

Send Email Failed Error: queryA EREFUSED smtp.gmail.com
    at QueryReqWrap.onresolve [as oncomplete] (dns.js:203:19) {
  errno: undefined,
  code: 'EDNS',
  syscall: 'queryA',
  hostname: 'smtp.gmail.com',
  command: 'CONN'
}

My code :

let transporter = nodemailer.createTransport({
  service: 'gmail',
  auth: {
    user: process.env.EMAIL, // generated ethereal user
    pass: process.env.PW_EMAIL, // generated ethereal password
  },
});

What is causing this? Is it a problem in the email or code? I have activated my email to less secure. Please help, thank you
