在部署的远程服务器上调试Django

Question

我在远程服务器上使用Nginx和Gunicorn运行Django。 我可以在远程计算机上（通过我的Web浏览器）进行某些类型的交互，这会导致Web服务器在将某些邮政操作执行Django后，使用“ 502 BAD GATEWAY NGINX/1.10.3（UBUNTU）”错误响应Web服务器。此错误恰好在30秒后重复发生。这让我认为这是与Nginx的某种超时。

当我在本地运行Django服务器时，一切运行正常。但是我认为这不是Nginx的问题，我认为这是远程系统上Django的问题。

有人可以提供有关如何查看远程机器上Django发生的事情的指导吗？或如何进一步调试此问题。

启用/etc/nginx/sites的内容： 我已经用xxx.xxx.xxx.xxx和服务器名称替换了我的IP地址 用“ myservername”

server {
    server_name xxx.xxx.xxx.xxx backend.myservername.com www.backend.myservername.com;

    location /static/ {

    location / {
        include proxy_params;
        proxy_pass http://unix:/home/django/my_django_project/django_subfolder/django_subfolder.sock;
    }
