Microsoft Bot Framework，调用外部自定义构建的API发送超时

Question

为了访问我的本地SQL DB（2014），我在NodeJS中开发了一个简单的REST API，使用的npm包是“ mssql”，我在邮递员中进行了测试，并在笔记本电脑中使用了本地的bot模拟器将解决方案部署到Azure时，收到超时错误：

节点REST API：

var sql = require("mssql");
var express = require('express'); // Web Framework
var app = express();

var dbconfig ={
     user:  "sa",
        password: "password",
        server: "myServer",
        database: "Reports",
        port: 1433,
        options:{
            encrypt: false
        }
}

var server = app.listen(8200, function () {

    var host = server.address().address
    var port = server.address().port
    console.log("app listening at http://%s:%s", host, port)

});

批号：

var builder = require('botbuilder');
var restify = require('restify');
var Request = require("request");

var connector = new builder.ChatConnector({
    appId:"apid",
    appPassword:"pass"
});
var inMemoryStorage = new builder.MemoryBotStorage();
var bot = new builder.UniversalBot(connector).set('storage', inMemoryStorage);

var dialog = new builder.IntentDialog();
dialog.matches(/^soporte/i, [
    function (session, args, next) {
        if (session.message.text.toLowerCase() == 'soporte') {
            builder.Prompts.text(session, 'Cual es el Ticket?');
        } else {
            var query = session.message.text.substring(8);
            next({ response: query });
        }
    },
    function (session, result, next) {
        // var resultado  = Consulta();
        var card = new builder.ThumbnailCard(session);

        card.title('Soporte');

        // card.images([builder.CardImage.create(session, profile.avatar_url)]);

        card.subtitle('Soporte en linea');
        var text = '';
        var cardTxt='';

        Request.get("http://ipaddress/customers", (error, res, body) => {
            if(error) {
                return console.dir(error);
            }
            console.log(body);
            text = JSON.parse(body);
            console.log(text);
            text = text.recordset[0]
            for(var myKey in text) {
                 cardTxt = cardTxt + myKey+": "+text[myKey]+" ";
            }
            console.log(cardTxt);
            card.text(cardTxt);

        });

            var message = new builder.Message(session).attachments([card]);
            session.send(message);

    }
]);

bot.dialog('/', dialog);

var server = restify.createServer();
server.listen(process.env.port || process.env.PORT || 3978, function () {
    console.log('%s listening to %s', server.name, server.url);
});
server.post('/api/messages', connector.listen());

错误：仅在部署时出现：
