Zoho with NodeMailer not working error code: 'EDNS'

I try to send an email with Nodemailer and always get the same error:

    hostname: 'smtp.zoho.com',
    secure: true,
    port: 465,
    auth: {
        user: 'maria@mydomain.my',
        pass: 'apppassgenerated'
    }
});

I tried too:

   service: 'Zoho',
    auth: {
        user: 'maria@mydomain.my',
        pass: 'apppassgenerated'
    }
});

I always get: { Error: queryA EREFUSED smtp.zoho.com at QueryReqWrap.onresolve [as oncomplete] (dns.js:213:19) errno: 'EREFUSED', code: 'EDNS', syscall: 'queryA', hostname: 'smtp.zoho.com', command: 'CONN' }
