Bluetooth is not available

Hello community,

i have a problem connecting my Logitech MX2 - mouse via Bluetooth.
I tried to reboot, shut down but i can’t activate it in the GNOME-control-center.

When I ask for status of Bluetooth via systemctl - command i get the following messages:

luetooth.service - Bluetooth service

Has anyone an idea which could be the problem?

Thank you.
