Hydrawise Binding - Controller Error


i recently noticed, that my controller is not being recognized anymore.
OH throws an Error:handler - HANDLER_INITIALIZING_ERROR
i configured it via things-file but also when i use the discovery function via UI it shows the same behaviour.

I tried to create a local controller instead but it also does not work. The controller is connected to my wifi and it has worked before.

I am running the latest milestone 4 of OH 3.3.0 on a debian Vm with openhabian tools.
