使用nginx -t测试时，我的配置中没有错误

root@proxy1:/var/www# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

然而，当我尝试运行systemctl restart nginx时，我得到以下错误。

root@proxy1:/var/www# systemctl restart nginx
Job for nginx.service failed because the control process exited with error code.
See "systemctl status nginx.service" and "journalctl -xe" for details.

运行systemctl status nginx.service返回

然而，我所有的网站运行在nginx的功能。
我在运行certbot时也会遇到与此相关的问题。
