Gunicorn failed to load Flask application
You're pointing gunicorn at mysite:app, which is equivalent to from mysite import app. However, there is no app object in the top (__init__.py) level import of mysite. Tell gunicorn to call the factory.
gunicorn "mysite:create_app()"You can pass arguments to the call as well.
gunicorn "mysite:create_app('production')"Internally, this is equivalent to:
from mysite import create_appapp = create_app('production')Alternatively, you can use a separate file that does the setup. In your case, you already initialized an app in manage.py.
gunicorn manage:app
