I am trying to access Keystone API. I get this error:

12:40 Module (OpenStack): HTTP error on [http://127.0.0.1:8774/v2/b45d434e73774f1dbc6bd97549fbd577/extensions], curl code [7] message [couldn't connect to host]

Output in keystone.log

keystone.conf

    [DEFAULT]
# A "shared secret" between keystone and other openstack services
# admin_token = ADMIN
admin_token = 018524a297d24cab91a735f3b50b00a1
debug = True

# The IP address of the network interface to listen on
# bind_host = 0.0.0.0
bind_host = 0.0.0.0

# The port number which the public service listens on
# public_port = 5000
public_port = 5000

# The port number which the public admin listens on
# admin_port = 35357
admin_port = 35357

# The base endpoint URLs for keystone that are advertised to clients
# (NOTE: this does NOT affect how keystone listens for connections)
public_endpoint = http://localhost:%(public_port)s/
admin_endpoint = http://localhost:%(admin_port)s/

# The port number which the OpenStack Compute service listens on
# compute_port = 8774
compute_port = 8774

Any ideas? I've played around exporting different variables. I can auth using admin and password, but not with endpoint and service token.
