Nodemailer fails with Client network socket disconnected before... even locally

import nodemailer from 'npm:nodemailer';

const testMail = async () => {
  const transporter = nodemailer.createTransport({
    host: "smtp.ethereal.email",
    port: 587,
    secure: false, // Use `true` for port 465, `false` for all other ports
    auth: {
      user: "tess3@ethereal.email",
      pass: "K9S6HKVEg8bDtVNnnr",
    },
    logger: true,
  });

  return transporter.verify();
}

testMail();
