您好，问题描述得比较详细了。还想问下前端访问的时候报的什么错误状态码？

nginx error.log看出来，nginx转发了动态请求，只是gunicorn服务接收的时候有问题，nginx服务没问题

daphne celery日志都正常，不过你gunicorn中为啥是listening at http://0.0.0.0:9000，不是127.0.0.1:9000？

如果错误状态码是500的话，你可以把debug开启，manage.py runserver来访问，看代码报错在哪里

  老师，现在确实变成500了
  “Ooops!!! 500
  Looks like something went wrong!
  We track these errors automatically, but if the problem persists feel free to contact us. In the meantime, try refreshing.”
  
  我把.env里的debug设成True然后关掉nginx redis supervisord，前端访问不到，直接502 Bad Gateway

  关于开启Debug老师能在详细说下步骤吗？谢谢老师！
