2024.10.1 -> 2025.4.1 KNX Integration doesn't work

Hi everyone!
Yesterday I updated from 2024.10.1 to 2025.4.1. After that my KNX Intergration didn’t work anymore. It seems like Home Assistant can’t connect to my IP Interface anymore. The Connection setting is “automatic”, but I also tried “tunneling” when it did not work. Does anybody has a clue what possibly could go wrong?

Almost my complete house is controlled by KNX, so I immediately installed my latest Backup and everything ist working fine again, but sooner or later I have to update my System.

I don’t think there were any breaking changes for knx recently.
When you do an update and something doesn’t work, make sure to have a look at the logs to get more details about what is not working.
Open your Home Assistant instance and show your Home Assistant logs.
