ruby-403在通过certbot Rails服务器安装ssl后被禁止

我安装了数字ocean rails图像，如图所示

然后，我按照安装letscrypt ssl的说明进行操作，并使其正常工作。然而，一旦SSL实现成功，我开始在主页上看到403错误。以下是错误日志：

2022/05/16 00:06:39 [error] 783#783: *11 directory index of "/home/rails/xxx-boxes/public/" is forbidden, client: x.x.x.142, server: xxx-boxes.com, request: "GET / HTTP/1.1", host: "x.x.x.62"

我不确定我应该在rails服务器上为root添加什么，应该是/home/rails/xxx。盒子或/home/rails/xxx。Box/public或其他东西，还是导致403错误的另一个配置问题？我确实试过在xxx上做chmod 775。但是没什么区别。在做了这些改变后，我重新启动了液滴，所以也不是这样。有什么想法吗？

我的文件在/home/rails/xxx中。盒子（如果名字不明显，我用xxx来掩盖它）
