Question

当我打开我的rails应用程序时，我收到504网关超时错误。

tail /var/log/nginx/error.log的结果：

upstream timed out (110: Connection timed out) while reading response header from upstream, client: 122.169.153.194, server: _, request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:8080/", host: "162.243.204.173"

然后，tail /home/unicorn/log/unicorn.log的内容：

您的后端独角兽工作进程崩溃，但您只包括堆栈跟踪的底部。 unicorn.log文件中的完整堆栈跟踪将显示应用程序代码中崩溃的内容。我猜错了中间件或反应不正确。
