结合cpanel的Nodejs-https

我正试图让https在我的nodejs服务器上运行,如下所示:

var http = require('http');
var https = require('https');
var fs = require('fs');
var express = require('express');
var privateKey  = fs.readFileSync('server.key', 'utf8');
var certificate = fs.readFileSync('server.crt', 'utf8');

var credentials = {key: privateKey, cert: certificate};
var app = express();

var httpServer = http.createServer(app);
var httpsServer = https.createServer(credentials, app);

httpServer.listen(8080, ()=> {
    console.log('Server started and listening on port 8080...')
});
httpsServer.listen(8443, ()=>{
    console.log('Server started and listening on port 8443...')
});

当我运行服务器时,只有http url在工作,https会超时。 知道为什么会这样吗?

我习惯于使用cpanel,所以我已经在那里设置了ssl证书,但是当涉及到node时,我遇到了麻烦。
