从iojs升级到Nodejs v4.4.4后，自签名SSL不起作用

我在应用程序中使用iojs和koa，最近我决定将iojs更新为nodejs v4.4.4。更新非常顺利，我的应用程序立即运行。问题是我在开发机器上使用了自签名SSL证书，更新到nodejs后，当我尝试访问网站时收到以下消息：

该网站无法提供安全的连接

本地主机使用不受支持的协议。

ERR_SSL_VERSION_OR_CIPHER_MISMATCH

The client and server don't support a common SSL protocol version or cipher suite. This is likely to be caused when the server needs RC4, which is no longer considered secure.

I am using nvm so I tried switching to iojs and the website was working again.

After some reading I found out that I have to update the openssl to version 1.0.2g instead of the 1.0.1g that I used to create the .key and .crt files. So I updated openssl and generated new key and certificate files like this:

sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/apache2/ssl/apache.key -out /etc/apache2/ssl/apache.crt

Sadly this did not resolve the issue.

This is the code that I use to setup the https on the server:

let sslOptions = {
            key: fs.readFileSync('/etc/apache2/ssl/apache.key'),
            cert: fs.readFileSync('/etc/apache2/ssl/apache.crt')
                 };

let server = require('https').createServer(sslOptions, app.callback())

Am I doing something wrong? Why does it work with iojs and does not work with nodejs?
