TLS连接未建立

Question

嘿，当我尝试向发件人的电子邮件地址发送电子邮件时出现错误。我正在使用节点邮件程序，并且已经共享了托管电子邮件帐户，当我尝试从该电子邮件帐户发送电子邮件时，出现如下错误：

Error occurred. Client network socket disconnected before secure TLS connection was established

这是我编写的节点邮件程序代码

 let transporter = nodemailer.createTransport({
                            host:'mail.abcdefgh.com',
                             port:465,
                             secure:true,
                            //  debug: true, 
                            // logger: true,
                            auth: {
                                    user: 'abcd@efgh.com',
                                    pass: '12345'
                                },
                                tls: {
                                    rejectUnauthorized: false
                                }
                        });
                        console.log(user);

                        // Message object
                        let message = {
                            from: '"Sachin" <abcd@efgh.com>',
                            to: user.email,
                            subject: 'You successfully registered for for the event',
                            text: `Welcome ${user.name.toUpperCase()} toour community`,
                            html:'<h2>Hello</h2>'
                        };


                        transporter.sendMail(message, (err, info) => {
                            if (err) {
                                console.log('Error occurred. ' + err.message);
                                return process.exit(1);
                            }
                            console.log('Credentials obtained, sending message...');

                            console.log('Message sent: %s', info.messageId);
                            // Preview only available when sending through an Ethereal account
                            // console.log('Preview URL: %s', nodemailer.getTestMessageUrl(info));
                        });
