Javascript http 服务器 : ERR_CONNECTION_REFUSED

Question

我最近尝试在我的服务器上安装 SSL 证书。证书文件(privkey.pem、fullchain.pem)位于应用程序的根目录中。当我运行以下代码时:

var express = require('express');
var app = express();
var helmet = require('helmet');
var db = require('./server/database.js');
var fs = require('fs');
var ssl = require('ssl-root-cas');

'use strict';
var rootCas = require('ssl-root-cas/latest').create();

// default for all https requests
// (whether using https directly, request, or another module)
require('https').globalAgent.options.ca = rootCas;

app.use(helmet()); 

var options = {
    key : fs.readFileSync('privkey.pem', 'ascii'),
    cert : fs.readFileSync('fullchain.pem', 'ascii')
}

app.get('/', function(req, res) {
    res.sendFile(__dirname + '/public/index.html');
});
app.use('/public', express.static(__dirname + '/public'));

var serv = require('https').createServer(options, app);

服务器运行没有错误。我添加的“服务器正在监听端口 80”确认显示，证书似乎不会导致任何直接问题。但是，当我尝试连接到域(使用 https://)时，Chrome 会响应 ERR_CONNECTION_REFUSED。通过 http 连接到域时，Chrome 会响应相同的消息。我正在使用稍后在代码中初始化的 SocketIO，我没有发现我的问题与 SocketIO 的功能之间有任何联系。无法连接是什么原因？

https 请求是通过端口 443 而不是 80 发送的。以下代码可以正常运行:

var express = require('express');
var app = express();
var helmet = require('helmet');
var db = require('./server/database.js');
var fs = require('fs');
var ssl = require('ssl-root-cas');

'use strict';
var rootCas = require('ssl-root-cas/latest').create();

// default for all https requests
// (whether using https directly, request, or another module)
require('https').globalAgent.options.ca = rootCas;

app.use(helmet()); 

var options = {
    key : fs.readFileSync('privkey.pem', 'ascii'),
    cert : fs.readFileSync('fullchain.pem', 'ascii')
}

app.get('/', function(req, res) {
    res.sendFile(__dirname + '/public/index.html');
});
app.use('/public', express.static(__dirname + '/public'));

var serv = require('https').createServer(options, app);
//var serv = require('https').Server(app); //DEBUG ONLY
