Gunicorn not starting even after succesfully configuring all files

I am working on a particular Django project (Don't know if this makes a difference but the service provider is Hostinger).. The deployment of the same is to be done on a vps server with ubuntu in it. Using gunicorn and nginx is what I have planned , but I keep on running into

502 bad gateway errorOn poking around found that gunicorn is not starting

The following is the error received when I ran

sudo systemctl status gunicorn

Error :

The following is my file structure :

The path to this is :/root/Assistanza/Assistanza

The following is the service file of gunicorn:

[Unit]Description=gunicorn daemon                                                                                                                                             Requires=gunicorn.socket                                                                                                                                                After=network.target[Service]User=rootGroup=www-dataWorkingDirectory=/root/Assistanza/AssistanzaExecStart=/root/Assistanza/Assistanza/env/bin/gunicorn \          --access-logfile - \          --workers 3 \          --bind unix:/run/gunicorn.sock \          Assistanza.wsgi:application[Install]WantedBy=multi-user.target~                                                                                                                                                                       ~        

How do I solve this ?

Update : So the error was the gunicorn was not running right in the virtual environment. To solve this I installed a new virtual environment and then installed gunicorn in that and saw that which gunicorn gave me the path to the file/env/bin/gunicorn.

and changed the service file path to this new venv and all is working fine.
