nginx+gunicorn+django+aws bad request

I was following a tutorial at http://ift.tt/1yUZa5b on deploying a django application. This is my current situation:

fab spawn instance created the aws instance with nginx and gunicorn installed but when I tried accessing the site on that machine I got a 400 Bad Request. I checked the nginx-error log but that was empty and the nginx-access log showed that it had received the requests. The supervisor log had the following:

I changed ALLOWED_HOSTS from [] to [''] and then '' When I changed it to the string, I got "The requested URL / was not found on this server." On other instances, I got 400 bad request.

This is the first time I am deploying a django app on nginx and I can’t figure out what the problem might be. Could you please help me debug this error? Thanks in advance!!

PS: Please let me know if I need to post any config files. So far I have just followed the tutorial and I have not changed any configurations.
