Cannot re-instal Qubino: get error "Homey is unreachable" (but it is not?)

Had trouble to add another Qubino device (Flush connector)
Every time I try I get an error “Homey is unreachable” try again. and I have tried a number of times, restarted homey, recovered it, deleted and re-installed Qubino app, but every time I tried or whatever I tried I get the error “Homey is unreachable”.
However, it is possible to install other apps like IKEA etc without any problem.

Does anyone recognize the problem??
Is there a workaround??
Any suggestions to successfully reinstall the Qubino app

There was an Maintenance outtime of some of the homey Services. Can you retry when all Services are up and running?
you can check the stauts over at status.athom.com

works now
