Troubleshooting AWS EC2 site connection timeout in browser

Troubleshooting AWS EC2 site connection timeout in browser

I am a newcomer to AWS, and am using the free tier to test personal Django
projects. However, when I try to access the IP address, the browser gives
a timeout error. The site works locally, and the timeout error shows when
accessing via wireless or wired connection.
The way I set up the site was using Bitnami DjangoStack, server is running
via ./manage.py runserver 0.0.0.0:8080 I also bound an available IP
address to the existing public DNS name. TCP Port 80 is open as HTTP with
a source of 0.0.0.0/0.
I executed netstat -aon and got the output
tcp 0 0 10.4.89.232:22 141.114.79.244:38928
ESTABLISHED keepalive (3582.28/0/0)
tcp 0 272 10.4.89.232:22 141.114.79.244:40393
ESTABLISHED on (0.21/0/0)
These two addresses are from my site access requests, and I'm using the IP
address and port 80 and 8080, but timeouts still occur.
The source code and database were set up via
Cloned git repository with site source code
Imported mysql dump into database
modified settings.py to reflect new database credentials
executed runserver command in server shell
No errors are showing up in the server logs. nmap produces
nmap -P0 -p80 54.2**.***.*
Starting Nmap 5.21 ( http://nmap.org ) at 2013-08-27 10:32 EDT

Any help is appreciated.
