Homematic IP hassio addon

After a restart of my hassio my homematic hassio addon has stopped working. I have done several restarts and reinstalled the plugin without success. One of the error messages I get is the one below. Anyone a clue ?

Hey, I have a similar problem. On a restart I lose the connection to all devices. The only fix in my case is to reset all Homematic IP devices and connect them again… Have you found a solution for your problem in the meantime?

Edit: Just found out that there is a bugreport available: https://github.com/home-assistant/addons/issues/1783
