My HomePods don't recognize my iCloud password

Hello,

I have a pair of HomePod 2, recently, Siri no longer works, asks me to go through the Home app of my iPhone 15P, which tells me that the iCloud password is incorrect, there is a button to enter the password that does not allow you to enter the password but tries to log in.

I tried to reboot, reset the Homepods, it works temporarily, Apple Care which seems to take interns recommended me to disconnect from iCould, Nada, any idea?

Thank you.
