Unit gunicorn.socket could not be found

I get a 502 Bad Request error after deployment with nginx.

I am using a digitalocean droplet.

Everything works fine locally, so I must have missed something while bringing over the files to filezilla...?

sudo journalctl -u gunicorn>

No journal files were found.

sudo tail -30 /var/log/nginx/error.log

sudo journalctl -u gunicorn>

No journal files were found

If your gunicorn.service files are not configured, the service is probably not running. You need to set up a service for gunicorn for the server to start, and nginx has a socket to read. I use the tutorial below for my OS, you can see something compatible for yours, most all steps are similar and have the same purpose.
