I am using a digital ocean server. After switching to mysql database from sqlite, I got 502 Bad Gateway nginx/1.18.0 (Ubuntu)
This is running fine when I run the project from the terminal using python manage.py runserver ip:8000 . I think there are faults in the gunicorn .
How to solve this any idea?
After checking the logs,
sudo tail -F /var/log/nginx/error.log
