Kostal Plenticore Binding stops providing new data after some time

Hi There,
Since some time I experience a problem that the Binding Kostal Inverter stops providing new information. It stays on Online and I got no log message from the Add-On at all. I set the LOG Level of org.openhab.binding.kostalinverter to INFO. All other bindings work as expected. After a restart the Binding works again for several hours. A disable of the binding and a reenable also sometimes resolve the problem, sometimes after the re-enabling it stays on unknown.

I think this issue persists since some time. But since approx. a month it got worse. I made changes to my PI. It got new works to do and is now internet accessible. But the new software is in a docker container that is why I think except more work on CPU (not exceeding) and Bandwith it does not changed anything which can influence the problem. In the past I thought it occured after a network connection break but I cannot actively reproduce the error by pulling the network cable.

I would really appreciate if you hava a tipp to get more details of openHAB or a solution for the problem.
