Gunicorn Configuration Fix on Ubuntu Server

I'm having trouble with Gunicorn not starting on my Ubuntu server. I'm using Django Rest Framework and React for my project. I've checked the Gunicorn error logs and found some configuration errors.

- Identify and fix Gunicorn configuration issues
- Ensure Gunicorn starts successfully on server
- Review server settings for compatibility

Ideal candidates for this project should have:
- Extensive experience with Gunicorn and Django
- Strong understanding of Ubuntu server configuration
- Ability to troubleshoot and resolve server issues promptly

Errors from "sudo journalctl -u gunicorn -b" include:
-"gunicorn.service: Main process exited, code=exited, status=217/USER"
-"gunicorn.service: Main process exited, code=exited, status=203/EXEC"
