Request for all that does not exist?

Hi folks, I keep seeing these in my logs; how can I find out where these are originating from ?

Thanks !

You may want to look up the device, 2504, that may give you a clue.

Did you used to have makerapi setup and remove it? Seems like something external is calling into your hub.
