Deconz AddOn no longer accessable

Hi There
just realized that I could no longer access the Deconz Addon throgh HA. The addon is running proprerly, but I could not open the application trough HA. It even does not ask for the user/password as before, just showin it looks for the gateway.
How to solve this? I have not changed anything, using the latest HA 2022.9.7 and Deconz 6.16.0.
