环境：

数字海洋Ubuntu 18.04 droplet，nginx安装，应用程序在Ruby on Rails中，使用capistrano进行部署。（它使用一个名为deploy的用户）
之前一切都很正常我在Digital Ocean上收到消息，然后我在Digital Ocean Ubuntu 18.04 LTS服务器上升级了一些软件包。从那时起，该网站已被打破，我得到403错误。
使用$nginx -V，我验证了版本从1.12.2升级到1.18.0
403 forbidden error

$sudo tail /var/log/nginx/error.log显示以下错误。

我重启了几次nginx。我也试过重新安装Rails应用程序。
我找到this link了。参见“权限被拒绝”部分。但在我的服务器上，没有文件/Users/phusion/Sites/rack.test。实际上，服务器甚至根本没有/Users或/Users/phpages文件夹。
我是个新手。任何帮助解决这个403错误是非常感谢。
