Hi support team,

I am facing an issue while trying to connect to compute unit.

ERROR (ClientException): The server is currently unavailable. Please try again at a later time.

The Keystone service is temporarily unavailable.

(HTTP 503) (Request-ID: req-9034590d-f5a9-4f6d-bcc1-de7705ab3487)

Below are the logs from placement: AH01630: client denied by server configuration: /usr/bin/placement-api AH01630: client denied by server configuration: /usr/bin/placement-api AH01630: client denied by server configuration: /usr/bin/placement-api AH01630: client denied by server configuration: /usr/bin/placement-api AH01630: client denied by server configuration: /usr/bin/placement-api AH01630: client denied by server configuration: /usr/bin/placement-api AH01630: client denied by server configuration: /usr/bin/placement-api AH01630: client denied by server configuration: /usr/bin/placement-api

Every service depends on keystone which is not running. Check the apache service and the respective logs on the control node
