I am trying to get deploy a FlaskApp with Gunicorn/WSGI/Nginx. I've been trying to get this to work for awhile and can't find any thing other than the Digital Ocean guides that I've followed to a T. Below are my files I've got in their current states. I have tried several different tweaks to mywebapp.service file because I am pretty sure this is where my problem lay. I can run /bin/gunicorn --workers 3 --bind 0.0.0.0:8000 -u nginx -g nginx wsgi and gunicorn will work. I'm pretty sure its some small possibly fundamental thing that I am missing but I lost. My nginx user owns the app directory.
