Kostal Binding can not use things for PICO10 in openhab3

Hey.
I tried this a view times. Also toggle the “Inverter Type” bevore save.
Still offline.
Also tried to do it via demo.things.

Thing kostalinverter:piko1020:piko15 [ url="http://192.168.156.91", username="pvserver", password="xxx", refreshInterval=60, hasBattery=false]

But this today not working :-/

What i think is strange, that the same config is not working anymore.
the openhab logfile is not very helpful either.
Same as in my other Thread:

Was there something interesting changed?
Is it maybe possible to test it via .jar file or something similar?

Thanks,
Tuffi
