Nodemailer运行主机

Question

我正在使用Nodemailer。我有几个正确运行在localhost中的表单，一切正常。但是当我将它们上传到我的主机（IP DigitalOcean）时，它们不会发送。

我做错了什么？或者上传到我的托管时我应该考虑什么。

我收到以下错误：

POST http://165.227.18.50/send 404 (Not Found)

xhr.send( options.hasContent && options.data || null );

我的IP正在运行：http://165.227.18.50/#!/inicio

server.js

var http=require('http');
var express=require('express');
var nodemailer = require("nodemailer");
var bodyParser = require('body-parser')
var app=express();
var port = Number(process.env.PORT || 5000);
app.use(bodyParser.json()); // to support JSON-encoded bodies
app.use(bodyParser.urlencoded({ extended: true }));

app.use('/', express.static(__dirname + '/'));


var path = require('path');

// Home page
app.get('/*',function(req, res, next){
    res.sendFile('index.html', { root: __dirname });
        //console.log 
        console.log('NodeMailer reading console log...' + req.url);
});

 
// sending mail function
app.post('/send', function(req, res){

    if(req.body.email == "" || req.body.seguro == "") {
        res.send("Error: Email & Seguro should not blank");
        return false;
    }

   // Sending Emails with SMTP, Configuring SMTP settings

    var smtpTransport = nodemailer.createTransport({

    }

 
    smtpTransport.sendMail(mailOptions, mailOptionsContact, function(error, response){
        if(error){
             res.send("No se pudo enviar el correo debido a un error.: "+error);
        }else{
             res.send("Requerimiento enviado con éxito.");
        } 
    }); 
});
