Freebox integration not working anymore with Iliadbox (Italy)

Hi, I’m having an issue with the Freebox integration. It suddenly stopped working a few weeks ago due to this problem https://github.com/home-assistant/core/issues/133246, but even if it says resolved it’s not working anymore for me.
I tried deleting and resetting the integration using the right settings (from http://myiliadbox.iliad.it/api_version), but when i click Submit nothing happens on the router (it should appear something to give permission to HA to access it). I tried dozens of times but nothing, only a few times it gave me the error “already_in_progress”.
I don’t know what to do anymore
