There seems to be some problem with your ‘admin’ password. Are you able to login to the Starlingx GUI/Horizon (http://<oam-floating-ip-address>:8080) with the admin as the user and the password you set for your admin user (should be part of your localhost.yml)

Subject: [Starlingx-discuss] an error when deploy starlingX

Hi all, 
  I follow the specification to deploy the starlingX 3.0.
  When I  configure controller-0 , i want to see controller-0 status,i meet an error with "unable to establish connection to http://localhost:5000/v3/auth/tokens".
  CLI command log list below.

 [sysadmin at controller-0 ~(keystone_admin)]$ source /etc/platform/openrc

 [sysadmin at controller-0 ~(keystone_admin)]$ system host-list

 Authorization failed:unable to establish connection to http://localhost:5000/v3/auth/tokens

 
  specification is from https://docs.starlingx.io/deploy_install_guides/r3_release/bare_metal/aio_simplex_install_kubernetes.html
  Please give me some advice. 
  Thanks
