nova error - ERROR (ConnectFailure): Unable to establish connection
I am trying to configure openstack mitaka in my local test environment which is of Ubuntu platform.
After configuring nova I am getting error.
I am unable to check the status of nova services.
Its showing an error:
root@controller:/var/log/nova# openstack compute service list
Unable to establish connection to http://controller:8774/v2/c93d2c39f4154f52bed4681d15890763/os-services
While I am checking the log I can see the error as follows:

Someone help me to fix the same.
The time stamps are very far apart and are unlikely to refer to the same problem. At which time did you run the server list command? Are you sure nova was running at the time of the command?
"Unable to establish connection" indicates that nova-api is not listening at this address and port; perhaps it has crashed? Also check the networking, for example, can you
ping controller, can youtelnet controller 8774etc.
