FritzTools UPnPError 820

The problem

Hi, I'm having problems with the fritz integration, it worked for a long time without problems, suddenly this error came out and it no longer allows me to integrate the fritz 6890, I haven't changed any settings in the router and in homeassistant, the integration works correctly with other Fritzes present in other homes, I tried to restart the router several times, disable and re-enable UPNP and TR-064 without success.
In the router events I read:
Access by an app with unknown registration name from IP address [IP address] failed.
The login details are correct and I have tried several times, I also created a new user but the same error always comes out, how can I resolve it?
