对于我的Adob​​e CEP 项目，我尝试从 Javascript 端通过 https 调用 REST API：

var xmlhttp = new XMLHttpRequest();
xmlhttp.open('GET', 'https://***/api/books', true);
xmlhttp.setRequestHeader('Authorization', 'Basic NDI5MDk...');
xmlhttp.send(null);
if(xmlhttp.status == 200) {
  alert(xmlhttp.responseText);
}

该代码在控制台中触发以下输出：

net::ERR_SSL_VERSION_OR_CIPHER_MISMATCH

查看对面的nginx服务器日志，只有一条错误信息：

2016/09/29 11:25:34 [info] 7048#7048: *4396957 SSL_do_handshake() failed (SSL: error:1408A0C1:SSL routines:ssl3_get_client_hello:no shared cipher) while SSL handshaking, client: **.**.**.**, server: 0.0.0.0:443

其他客户端连接到服务器没有问题。Web 服务器非常稳定且维护良好，运行 TSL 1.2 并支持所有安全密码：

这里发生了什么？什么是适当的调查方法，更好地解决这个问题？
