I don't have enough reputation to reply above, but you could also check the latest syntax from Nodemailer, ie:

 const smtpConfig = {
     host: 'smtp.gmail.com',
     port: 465,
     secure: true, // use SSL
     auth: {
       user: '[email protected]',
       pass: 'pass'
     }
 }

note:

 secure: true // use SSL

You might not need that TLS work-around if you tell it to use SSL.

Reference: https://nodemailer.com/2-0-0-beta/setup-smtp/

Mine is currently running off postfix and mailx, and I only had to put in the hostname:

 const transporter = nodemailer.createTransport({
          name: 'localhost'
 })

That should work as long as you can perform this test (type in shell):

 echo "Email Body Test" | mail -s "Email Subject Test" [email protected]

If it doesn't work, investigate your firewall, port 25 (probably not the issue in this case, but in other similar cases).

Also confirm the user running node has permission to use the mail program.

I had similar problem (maybe the same) and I figure out that this happens when i use self signed SSL certificate. I fixed this by adding "rejectUnauthorized" option to tls:

var transporter = nodemailer.createTransport(smtpTransport({
    host: host,
    port: 25,
    auth: {
        user: user,
        pass: pass
    },
    tls:{
        rejectUnauthorized: false
    }
}));

The error is applied to the callback of "sendMail" function and is not emitted as 'error'.
