i have looked across internet, including stackoverflow, , have seen similar problems, after several hours stumped.
i can add in information thinks might of use. on digitalocean droplet ubuntu14.0.4, in virtualenv named 'sod22', python3.4, django1.8, gunicorn19.4.5, nginx1.4.6 here error output in bash:

[2016-01-27 02:25:23 -0500] [25609] [error] can't connect ('0.0.0.0', 8000) i have checked processes might running on port 8000 using netstat:
(sod22) root@shapeofdata2:~/.virtualenvs/sod22# netstat -tulpn active internet connections (only servers) proto recv-q send-q local address foreign address state pid/program name tcp 0 0 0.0.0.0:80 0.0.0.0:* listen 16069/nginx tcp 0 0 0.0.0.0:22 0.0.0.0:* listen 3411/sshd tcp 0 0 127.0.0.1:5432 0.0.0.0:* listen 14574/postgres tcp 0 0 127.0.0.1:8000 0.0.0.0:* listen 25638/python3.4 tcp6 0 0 :::80 :::* listen 16069/nginx tcp6 0 0 :::22 :::* listen 3411/sshd i have killed gunicorn processes, same behavior. however, different command console seems 'lock up' , there still no output web page:
(sod22) root@shapeofdata2:~/.virtualenvs/sod22# gunicorn sod22.wsgi:application [2016-01-27 02:27:17 -0500] [25638] [info] starting gunicorn 19.4.5 [2016-01-27 02:27:17 -0500] [25638] [info] listening at: http://127.0.0.1:8000 (25638) [2016-01-27 02:27:17 -0500] [25638] [info] using worker: sync [2016-01-27 02:27:17 -0500] [25641] [info] booting worker pid: 25641 at point there no cursor try else, without killing console @ point.
per sayse's advice, checked out processes , results after killing processes. maybe python using port:8000 , continuously refreshing after killed? see below, note after process killed, check again, , running again:
