Changing the hostname of an on-premise appliance can have consequences that result in services not starting.
It is possible that the name of the appliance was changed during the initial deploy of the OVF when the NetworkManager TUI screen was displayed. Restoring the name back to default may present challenges if you do not have root access to the appliance.

How to access the NetworkManager TUI
What the default setting is for the system hostname
The ability to log into the appliance as root depends on whether you have the flag in your license file. In the past, this was handled via a separate agreement, however now it is part of the standard agreement so you can have your license reissued with the root password permission included.
This article discusses how to change your root password from the control panel as well as how to request the license to get the permission to change root password: https://comm.support.ca.com/kb/requesting-and-updating-the-root-password-for-the-agile-central-onpremise-appliance/kb000010888
