You may need to add u'127.0.0.1' to ALLOWED_HOSTS

I am getting the following error when I am trying to start my Django server

I have already given 127.0.0.1 in the list of ALLOWED_HOST.

SECRET_KEY=BeatTheStreet

DEBUG=True

ALLOWED_HOSTS=['127.0.0.1', '0.0.0.0']

EVENT_STARTED=True
EVENT_ENDED=

# Production database details
DB_NAME=
DB_USER=
DB_PASSWORD=
DB_HOST=
DB_PORT=

Pointers to fix this will really help.

I am running server with 0.0.0.0:8000 because of issue I had in Django app not opening from different machine

This happens just because localhost of your host machine is not localhost of your host server. You can either do

ALLOWED_HOSTS=['<your host ip address>',]

or

ALLOWED_HOSTS=['*',]

although wildcard is not recommended, but useful in dev mode.

in the given ifconfig, the inet addr 192.168.1.104 is the ip of your host machine, if run ifconfig in the host
