Problems with the 'How To Set Up uWSGI and Nginx to Serve Python Apps' tutorial

I’m going this tutorial

https://www.digitalocean.com/community/tutorials/how-to-set-up-uwsgi-and-nginx-to-serve-python-apps-on-ubuntu-14-04

Im up to the part where this command needs to be run

uwsgi --socket 0.0.0.0:8080 --protocol=http -w wsgi

and then I should be able to see the ‘Hello there’ message at my server ip + :8080 (its 128.199.97.37 btw)

however nothing seems to happen, in Chrome it appears to be loading something very slowly and eventually I get a message

'This site can’t be reached

128.199.97.37 took too long to respond.’

uwsgi appears to be running ok in my terminal with no error messages, here it the output:

Ive checked the wsgi.py file and everything is the same as in the tutorial. No .ini file has been set up yet though as I have not reached that part yet.

If anyone can advise that would be great thanks
