I did not, I just used the above commands which you mentioned, after that I faced this error.

Hi there,

You would see a 502 error when the backend service is not running.

Is the Gunicorn service running? You can check that with this command:

sudo systemctl status gunicorn

If it is not running make sure that it is started:

sudo systemctl start gunicorn

Also you can enable the service, so that the next time the server reboots, it would start automatically:

sudo systemctl enable gunicorn

Let me know how it goes. Regards, Bobby
