Unhandled Exception An unhandled exception was thrown by the application.
"

The Story when i try to deploy a new code in new staging server on aws ec2. 
i was intalling anything before. library, dependency and etc 
but when i'm running it i got an error message

"Unhandled Exception An unhandled exception was thrown by the application."

WTF. did i miss something ?? I'm not preparing for any watchdog things. because its a new server. 
Im trying to trace the logs by /var/log/nginx/ but i didn't found the real error. 
i also enable DEBUG=TRUE and the result still same "Unhandled Exception An unhandled exception was thrown by the application."

I think i should running python manage.py runserver to see the real error. 
because i'm usually running the code in server by runfcgi associated with nginx config.

let's try with public ip 59.120.48.109:8000
python manage.py runserver 59.120.48.109:8000

Yeah. it works !!? so then how i check/watch the error in my browser while the ip addr is local ip ?? 
LOL this is sick man.. 

Ohh Wait !! I got an Idea.

I login to my server over ssh in another terminal while keeping my first terminal session open. 

then I do 

$ wget http://127.0.0.1:8000/
--2016-04-19 05:03:42--  http://127.0.0.1:8000/

HTTP request sent, awaiting response... 500 Internal Server Error
2016-04-19 05:03:42 ERROR 500: Internal Server Error.

what the hell. WGET ??

So, lets see in first terminal. is there any error message shown up ? 

YES..

python manage.py runserver
