2503 Bug found. You can't create PVS Machine Catalogs in Web studio with the service account previously entered. If you put in the same credentials for that service account into the login credentials it works fine. Those stored credentials work fine for MCS machine creation.

wish there was some integration with things like Cyberark. We rotate our service accounts used for join and delete operations daily.

my hosting connection also needed to re-enter the password. all vms run powerstate unknown. May this is caused by other certificate handling? Do you have a self-signed cert on your HV Connection?
