程序正常运行一段时间，就莫名出现 504 Gateway timeout about uwsgi-nginx-docker HOT 2 CLOSED

I'm sorry, I don't speak Mandarin. I "google translated" it, and I see you are having 504 Gateway timeout errors. It's possible that your app code has a bug somewhere and breaks. But Nginx keeps trying to speak to uWSGI and waits for it to answer. And then it shows the timeout error. But it's probable that the code actually had an error before at some point.

To see the logs you can use docker logs commands: https://docs.docker.com/engine/reference/commandline/logs/

from uwsgi-nginx-docker.

sudo systemctl restart docker

sudo usermod -aG docker $USER

and relogin your shell

from uwsgi-nginx-docker.
