failed (111: Connection refused) while connecting to upstream

I am getting failed (111: Connection refused) while connecting to upstream error in my nginx error log file while trying to access the Django app on my droplet. I understand that the issue my be that nginx is not finding gunicorn. I tried to start gunicorn but getting “start: Unknown job: gunicorn” error, I even tried restarting the droplet but still getting the gunicorn “unknown gunicorn”.

There is also nothing getting printed in my gunicon.log file. I also tried the solutions on similar posts on DO but nothing works

Any help will be highly appreciated, been having this issue for two days with no clue
