Gunicorn - start server issue? How to start it?

I am having this issue to start my gunicorn server, but it seems like it’s failing to start the server after I did reload daemon and enable my updated gunicorn system. I checked two or three times to make sure all’s correct, so alls correct. Pls see the image-link below: enter image description here - Also, see the errors I received after I started it:

Active: failed (Result: resources)

Anyone here is familiar with this issue? Your help would be so appreciated!

Thank you!
