Apcupsd deamon not reading

Hello,

I have a apcupsd question.

I did install the apcupsd deamon integration in HA (running on VM on a windows 10 machine).
It does recognise the ups (correct name, type and firmware deamon version are shown as info), but all sensors are ‘unavailable’. It used to work, but I don’t know when it stoped working.
When I shut down HA the deamon monitior in windows does show all values.

What can I do to get the data into HA?
