How To Serve Flask Applications with Gunicorn and Nginx on Ubuntu 20.04

Connected Tutorial
This question is a follow-up to this tutorial:

Hi,

Followed the tutorial on Flask/Gunicorn/Nginx/Ubuntu20.04 and am having a problem at the point where Nginx connects to the myproject.socket file. Client request results in an error in /var/log/nginx/error that reports ‘Permission denied’:

*3 connect() to unix:/home/user/myproject/myproject.sock failed (13: Permission denied) while connecting to upstream, client: …, server: … , request: “GET / HTTP/1.1”, upstream: “http://unix:/home/user/myproject/myproject.sock:/”, host: “…”

Have tried 777 permissions on the socket file and changes to the permission on the parent dir with no success. Any ideas? Could it be an issue with the www-data user’s memberships?

I have the exact same problem. So assuming your DNS settings are okay, the solution is simple: Set up based on https://www.digitalocean.com/community/tutorials/how-to-serve-flask-applications-with-gunicorn-and-nginx-on-ubuntu-20-04 but as a User and not as root. :)
