When adding the Utility Appliances to the Utility Appliance Group you get this error :
PAM-UTL-0110- Failed to update Utility Group Cluster <cluster_name> because the following number(s) are not ready yet. <name1><ip_1> <name2><ip_2>. Please try again later.
The PAM version currently installed is PAM 4.2.0.826, The Utility Appliance OVA that was deployed is named "Privileged Access Manager Utility Appliance r4.3.ova"
There is a mismatch of UA version regarding the current PAM
Installing and deploying the correct ova in acordance with the PAM Version fixes the problem.
