We got a couple of Daikin airco's that have been working flawlessly ever since I started using HA 2-3 years ago. Today, after an upgrade to 2024.8.1 all of them stopped working. The visible error message in the integrations reads:

When checking the logs I see two errors related to Daikin integration. See below for these...

I just deleted the integration, since my AC had lost connection with the home network. After having got it back online via the Daikin app, HA discovered the unit, with the correct IP address. Selecting configure and pressing send (IP address is already filled in) only results in an "unexpected error" message however. It's a unit with built in WiFi adapter, with no local API, so the configuration only wants the IP address, and not any API key or password.
