Bosch Indego, How to use Bosch single ID

Hi,

since yesterday (at least that’s when I realized it) the authorization keeps failing with this error:

2023-11-05 09:59:35.974 [INFO ] [internal.handler.BoschAccountHandler] - Attempting to authorize using authorization code

It worked for quite some time now, and on commandline I also do not get an error when I authorize the bridge:

openhab> openhab:boschindego authorize eyJraWQiOiJoYURfVWlBTXE3Q2t4WXpGRUp .... many other characters ... w.MVuMZyUSowpyYz9Q5DvJOA
openhab>

Did Bosch change something in the authorization again?

I also tried to create a new thing - but this also didn’t help.
