should be yes, it is a UCS Default installation.
the UCS Gui is there to login:
Interner Server-Fehler: Der Dienst ist momentan nicht erreichbar!
The Univention Management Console Web Server could not be reached. Please restart it or try again later.
strange because it is localhost to reach!
ssh to the UCS system and doing a
univention-management-console-web-server.service loaded failed failed LSB: Univention Management Console Web Server
# systemctl start univention-management-console-web-server.service
takes a whil to execute but after it is loaded active running
? univention-s4-connector.service **loaded failed failed** LSB: Univention S4 Connector
again doing a start take a while then it is there but the status say:
Sep 15 17:06:30 ucs01-mgmt1 systemd: univention-s4-connector.service: Supervising process 13710 which is not our child. We'll most likely not notice when it exits.
and in the GUI there is no login file anymore just the Portal background image - with no option to login and no visible app
