You can fix it adding

tls: {
    rejectUnauthorized: false
}

like @ty2k suggest to the transporter object. Or maybe its your antivirus, I cancel my Avast shell and now its working.

email: {
    smtp: {
        host: SMTP_HOST,
        port: 465,
        secure: true,
        requireTLS: false,
        auth: {
            user: SMTP_USERNAME,
            pass: SMTP_PASSWORD,
        },
    },
    from: EMAIL_FROM,

There is a good discussion about using Nodemailer with self-signed certificates in this GitHub issue. Specifically, this post can help get rid of the error message:

If you know that the host does not have a valid certificate you can allow it in the transport settings with tls.rejectUnauthorized option:

var transporter = nodemailer.createTransport(smtpTransport({ host: "outmail.abc.co.th", // hostname secure: false, // use SSL port: 25, // port for secure SMTP auth: { user: "[email protected]", pass: "passwordmail" }, tls: { rejectUnauthorized: false } }));

However, if you believe the mail services you are trying to use have valid certificates, you might have a local issue with your machine or network.
