我在远程Arch Linux服务器上安装了Nginx。我在/srv/http/mywebsite.com中有文件。（“mywebsite.com“当然只是我在这个问题中使用的占位符名称。
在那个目录中有一堆文件和页面。没有index.html。直到最近，我还可以通过访问mywebsite.com来查看目录中的所有文件。但是现在，在运行yay -Syyu升级和更新包，并删除/var/spool/clientmqueue中的文件后，当我转到mywebsite.com时，我只看到Nginx默认的“欢迎”页面。
以下是/etc/nginx/nginx.conf的内容。` #user http; worker_processes 1;

}在/etc/nginx/sites-available和/etc/nginx/sites-enabled中，我都有mywebsite.com，其内容如下.server { listen 443; ssl on; ssl_certificate/etc/ssl/cert_chain. crt; ssl_certificate_key /etc/ssl/myswebsite.com.key;
