[Django]-NGINX 502 bad gateway gunicorn timeout

I figured it out. In my gunicorn.service file in /etc/systemd/system/gunicorn i service.
I made a change:Added the time out. Default time out for gunicorn is 30 sec so I updated to 120.

[Unit]
Description=gunicorn daemon
After=network.target

[Service]
User=lisa
Group=nginx
Restart=on-failure
WorkingDirectory=/home/lisa/revcon
ExecStart=/home/lisa/revcon/env/bin/gunicorn --**timeout 120** --workers 5 
--bind unix:/home/lisa/revcon/env.sock revcon.wsgi:application

[Install]
WantedBy=multi-user.target
~

And it worked just fine for me.
