Xiaomi aquara invalid key

Hello everyone
I’ve configured my aquara gateway long time ago, today it does not want to work.
It’s give me ‘Got error element in data {“error”:“Invalid key”}’ error, the strange thing is that the light turns on if I want to, but HA don’t recive any message to update the state.
I’ve tryed to renew the key, generating it with my mi mix 2s and my kindle too, but HA gives me back error in the key and the switch doesen’t work.
PS I use hassbian but I’ve made some test on my pc with docker too… same results
