ahhhh… I see… I have to start the service.
@robb Thank you for the hint.

why is the state “deactivated” also if I start the service and he is running?

The service is started (running) but won’t be auto-started at boot unless the service is also enabled.

https://www.freedesktop.org/software/systemd/man/systemctl.html
Enabling units should not be confused with starting (activating) units, as done by the start command. Enabling and starting units is orthogonal: units may be enabled without being started and started without being enabled. Enabling simply hooks the unit into various suggested places (for example, so that the unit is automatically started on boot or when a particular kind of hardware is plugged in). Starting actually spawns the daemon process (in case of service units), or binds the socket (in case of socket units), and so on.

From cockpit services page, you can enable it from the kebab/hamburger options menu.
