[SOLVED] Loxone binding authentication issue

update : I was running openhab on QNAP and it was version 2.2, the binding for Loxone was also 2.2. Updated openhab to 2.4 (QNAPClub) and got Loxone 2.4 binding, which is working

Hi,
I cannot activate the binding with Loxone.
I tried through the PaperUI, and even through a loxone.things file.
I am 100% sure that the credentials are correct.
I ensured that I have the crypto unlimited setting in my JRE, and I tried different account in Loxone and different authMethod settings.
Running Loxone 10.2.3.26
First attempt gives UNAUTHORIZED, second attempt a 4003 error (IP blocked)

Some logging :
