Installation guide

d. If you are running Django 1.5 (or later), you must ensure that there is a correctly
configured ALLO WED _HO ST S setting in your l o cal _setti ng s file.
ALLO WED _HO ST S contains a list of host names that can be used to contact your
Dashboard service:
If people will be accessing the Dashboard service using
"http://dashboard.example.com", you would set:
ALLOWED_HOSTS=['dashboard.example.com']
If you are running the Dashboard service on your local system, you can use:
ALLOWED_HOSTS=['localhost']
If people will be using IP addresses instead of, or in addition to, hostnames, an
example might be:
ALLOWED_HOSTS=['dashboard.example.com', '192.168.122.200']
Note
For more information about the ALLO WED _HO ST S setting, see the Django
Documentation.
