HomeKit binding stopped workting after update

Hi,

after last openHABian update, based on this thread I have the issue that HomeKit is not going online again. It worked good so far and I was happy beeing able to control my lights via Siri. The eventlog shows this when I start the Home App on my iPad and it tries to reach openHAB. For me it looks like the Binding is blocking:
