可能的Nginx代理问题

Question

我的任务是使用nginx修复我公司的一个演示站点中的一些问题。我以前接触nginx的机会非常有限。

当前，当某人导航到https://blah.demo.site.com并单击指向其他任何页面的任何链接（例如产品页面）时，他们被发送到https://blah.demo.site.com/blah/products并收到错误404。我们想要发生的是点击实际发送到https://blah.demo.site.com/products

的链接

以下是/etc/nginx/conf.d/中我们当前的nginx配置文件。我如何弄清楚我们在做错什么？

server {
  server_name blah.demo.site.com;

  access_log /home/company/site/current/log/blah_nginx.access.log;
  error_log /home/company/site/current/log/blah_nginx.error.log info;

  client_body_buffer_size 128k;
