在我从github上提取了一些更新之后，我的网站目前已关闭。
我已经尝试过sudo systemctl restart gunicorn和sudo service nginx reload，但它们无法解决问题。
我已经检查了/var/log/nginx/error.log，内容为：

这使我认为服务器错误是由于该图像文件在服务器上不可用所致，因此我从主HTML模板中删除了对此文件的请求。
运行sudo nginx -c /etc/nginx/nginx.conf -t返回：
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
为了安全起见，我已将对域的引用更改为“ example”，并更改了服务器IP地址。
