I am working at my django project with nginx and gunicorn, as it said here:
https://www.digitalocean.com/community/tutorials/h
proxy_pass http://unix:/root/myproject/myproject.sock;
The socket is in the superuser's home folder. That's pretty much inaccessible to all other users including your nginx users. Please more the socket to a different location. /var/log/gunicorn/ is a good place.
Also do i see you running gunicorn as root?. Not recommended.
setuid root
Please use some other user here.
