Rails 4 + nginx + unicorn + ssl = 502坏的网关

浏览器显示502坏门户 – nginx。 唯一的好消息是我的SSL HTTPS和绿色锁正在显示。

下面的Nginx日志错误

nginx的/ error.log中

*1 connect() failed (111: Connection refused) while connecting to upstream, client: xx.xxx.xx.xx, server: mysite.com, request: "GET / HTTP/1.1", upstream: "http://xxx.xxx.xx.xxx:80/maintenance.html", host: "mysite.com" 

home / unicorn / log / unicorn.log （好像在等待nginx）：

• 504网关超时nginx / 1.4.6（Ubuntu）
• 好独angular兽+ nginx + cap部署howto？
• 我如何使用nginx和Unicorn托pipe多个Rails应用程序？
• 错误的IP地址与nginx +独angular兽+轨道
• 如果空闲，Rails将停止响应
