Alexa home made skill not connecting to HA

Hello there,

Since yesterday, my Alexa skill is not connecting HA.
I can’t “link the skill” anymore

The login page of HA is showing, my credentials are correct, the 2FA is showing and after a few seconds, I have the above screen.

So I’ve done some tests.
Using the api in postman is succesfull

But the same in the AWS developer console is giving me a timeout (same BASE_URL)

It is the same external URL.
My Dasboard is reachable with the same URL.
Why is the lambda not able to connect intime to my HA instance?

Any idea to explore?

P.S.: I’ve even created a brand new lambda, using Python 3.12 (instead of 3.7, 2 years ago) but it is also unsuccesfull :cry:
