Gardena smart system bindings connection error openhab 3.0.1


I am using the Gardena binding and I have connection problems with the smart system account.

The connection only works very rarely. Most of the time the binding goes into error or remains in initializing.

I renewed my API key but that did not solve the problem.

What can I do to correct this problem? Thanks for your help.

Here is what I see in the logs:
