Neato-Binding (Vorwerk VR200) not working anymore: Error connection nucleo host


like described in Connecting Vorwerk Kobold VR200 to openHAB2
I connected my VR200 to openhab and this worked fine until I updated to openhab 2.2.0 stable.
Now it don’t work anymore and every 10min I get the following errors in openhab.log:

In PaperUI I can see the thing with status offline. It looks like this:

in karaf-console I can see that the binding is active:

I switched to openHAB 2.3.0~20180406103010-1 (Build #1251) but that didn’t help.

Like I mentioned above, with openhab 2.1 it worked fine.

Can somebody help me? @fatman42285 @Giga522 @scurb ?

Have you already tried to start up all over again by deleting the binding, creating a new thing and login to your account?
have you installed: feature:install openhab-runtime-compat1x?
My openhab 2.2 release version is still working.

Yes I think so.
After deleting the thing PaperUi discovered it again. I renamed the jar file to jar_OFF and after a reboot it didn’t appear in karaf bundle:list anymore. Then I renamed it back to jar. Also did the install command.
With the vorwerk-app I can log in and can control the vr200.
But I will try once again tomorrow.

Today tried to start up all over again, but openhab stops as soon as I want to work with PaperUI.
Other bindings do not work properly anymore.
There seems to be a general problem with my openhab installation.
Must do a more accurate troubleshooting.
Thanks so far.
