Hi Christian,
Your control agent will be trying to communicate with kea-dhcp4 using
the socket "/var/run/kea/control_socket" but the kea-dhcp4
configuration doesn't have that socket configured. See detail here:
https://kea.readthedocs.io/en/kea-2.2.0/arm/dhcp4-srv.html?highlight=socket#management-api-for-the-dhcpv4-server
Thank you,
Darren Ankney
