我有一个停靠的Nginx代理，它位于我的服务器上。

我的一个网站是Docker Compose Wordpress网站。它们是单独的容器，必须保持这种状态。

When I update my Site Url in the Settings I can still log into my Admin Dashboard, but I cannot reach my actual site. I receive a 502 Gateway Error from Nginx.

Nginx服务器块：

   server{

        listen 80;
        server_name test.com;
        client_max_body_size 2M;
        location / {
          proxy_pass http://XXX.XXX.XXX.XXX:8001;
        }
   }
