Sounds like an installation issue (something about the host's
networking). Horizon normally has no issues talking to a keystone on the
same host.

Title:
   Unable to establish connection to keystone on same machine

Status in OpenStack Dashboard (Horizon):
  Invalid

Bug description:
  Both Horizon, for the front-end, and Keystone, for the back-end
  installed in the same machine .

  Keystone:
  I config in keystone/etc/keystone.conf:
  public_bind_host=10.30.176.40
  I wil check Keystone, it's work.

  In horizon/openstack_dashboard/local/local_setting.py, I config :
  OPENSTACK_HOST = "10.30.176.40"
  OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3"; % OPENSTACK_HOST

  And start Horizon by command :
  $sudo tools/with_venv.sh python manage.py runserver 10.30.176.40:8000

  But Horizon Unable to establish connection Keystone.
