I see a constant stream of messages like this in my AppDaemon logs for a few days now:

I did not touch AppDaemon or its configuration.
All I did, was update HA to 2025.7.3 but the problems did not occur right after that.
Restarting AppDaemon, HA oder the whole host HA runs on does not change the situation and I’m fairly clueless, what the source of the problem might even be.
(As a result my 3 NSPanel devices are currently not displaying anything.)
I run HAOS and AppDaemon inside it. So it’s all local talking.
Can anyone push me in the right direction?
Addendum:
On the HA side I see this:
