Bug Description

Brief Description
-----------------
Setup: I have StarlingX duplex mode setup up and running. I am able to spawn VMs on it.

Test Case: Testing instance HA.

Issue: After active node reboot, I am not able to take ssh on standby node. The console stucks on standby node and I don't see the the hostname where we enter commands. The overall system went down. The rebooted node comes up but not able to see anything on it as it is showing keystone unavailable. No StarlingX GUI and openstack services are available at this time.

Steps already taken : Rebooted both the nodes again to bring the setup in stable state again.

Can you please help me to find the reason of this.
