ZHA suddenly down?

Hi,

I’m on vacation and not at home…

Two days ago I suddenly received a message (via a self-written automation) that my Philips Hue smart plugs were no longer available. Shortly after that, my Hue motion sensors also failed.

In the meantime I have done all available updates and restarted both ha and the server (via ha), but nothing helps.

In the log I only see this:

What can I do else ?
