python on a cloud server

[IMuriel]

Hi im pretty new in python, so im already have a simple app runing locally, and im trying to make it run on digitalocean droplet, with ubuntu 16.04 tls

evryting is ok for now i have installed my virtualenv, and nginx, so im trying to use gunicorn, but something might be wrong cause, i cant see the index of my app


hope you can helpmeout
wsgi.py file

 
import os, sys
sys.path.append(os.path.abspath(os.path.join(os.path.dirname(__file__),'..')))

from flask_blog import app

if __name__=="__main__":
        app.run()

when i use gunicorn --bind 0.0.0.0:8000 wsgi:app
im getting the following

[2019-01-25 19:48:59 +0000] [7179] [INFO] Starting gunicorn 19.9.0
[2019-01-25 19:48:59 +0000] [7179] [INFO] Listening at: http://0.0.0.0:8000 (7179)

[2019-01-25 19:48:59 +0000] [7182] [INFO] Booting worker with pid: 7182

and when i try to acces to my app, it just dont change, so appears that unicorn cant reach my app :(
