Following this tutorial, https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-16-04, I have done everything exactly, including the server setup guide at https://www.digitalocean.com/community/tutorials/initial-server-setup-with-ubuntu-16-04, and at the first launch of the application: manage.py runserver, it runs the server, but visiting that particular ip address and port 8000 gives absolutely no response. Has there been changes in versions that have made the above documentation obsolete? Or maybe a step that needs to be done but hasn’t been included? I’ve tried 5 times now on 5 new droplets, following the documentation exactly… So first we call rule out typo’s and such…
