I have using nodemailer to send emial notification in my system, and it works perfect before this week. I got an error said cannot use IPV4 address with current network

{ Error: Can not use IPv4 addresses with current network

    at GetAddrInfoReqWrap.onlookupall [as oncomplete] (dns.js:80:8) code: 'EDNS', command: 'CONN' }

Some info related to my system and application:
System: Ubuntu 22.04.
Backend: express.js.
Node.js version: 10.19.0.

const nodemailer = require('nodemailer');

const transporter = nodemailer.createTransport({
service: 'gmail',
auth: {
user: '**',
pass: '**',
},
});

function sendEmail(to, subject, text, html) {
transporter.sendMail({
from: '"Server - donotreply" <mailto:*******@gmail.com>', // sender address
to: to, // list of receivers
subject: subject, // Subject line
text: text, // plain text body
