deviceUnknown

I'm receiving several deviceUnknown logs, even though the device is already registered on the platform.

I think you're confusing two very different logs. This is just an event for when device connection status changes to unknown. It's not the same thing as device unregistered.

Got it.

Because it looks a lot like the log:

2025-05-29 11:43:36 WARN: Unknown device - 868022037010530 (187.32.97.125)

Thanks.

It looks a bit similar, but not the same.

Thanks @Anton for clarifying. I started to notice these as well when I moved to
<entry key='event.forward.type'>mqtt</entry>

They mainly occur just before the item (phone, car e.g.) sends an http request to traccar just before they become deviceOnline

I can easily filter these out, thanks!

It just means that your device hasn't reported data for some time. By default the timeout is 10 minutes.
