Has anybody ever seen the following log error or, more importantly, what it takes to fix it?

I’ve got no idea where to start looking since all of my ping device trackers seem to be working.

Same error here. No idea what’s causing it.

Similar here, also ping component. However in my case caused by a binary sensor ping. I also logged an issue on git, HA_core:

https://github.com/home-assistant/core/issues/41710

Traceback:
