Nabu Casa Token refresh fails

I have two Home Assistant instances on two different locations. Both updated to 2024.6.2 One is HA-OS and the other is HA Core Container.
In both places I have several Netatmo cameras installed.
Everything has been working perfect for a long time.
Today, the Netatmo Integration fails to load in my HA-OS instances. I get this error message:

On my other HA instance (HA Core), the Netatmo Integration loads just fine.
What could have caused this, and what can I do to debug/fix this problem?

I have the same problem with Netatmo since the last update. What to do? Remove and reinstall?

Yes, I deleted the integration and reinstalled it. Now it’s ok again.

Yes , that did the trick.
