While looking threw my logs today, I noticed this. Would anyone be able to shed some light on what they are related to? Seemed odd to me.

Kevin - did you find out the reason for these log entries?
I have the same here.

Kind regards,
Hajoka

Is your OH server exposed to the outside?

I have similar issue on OH3, can we block this from OH side? My OH is exposed via NAT to Internet
Please advice?
Kind Regards,

Slawek

Here is some advice: Don’t expose your openHAB to the internet unless you know what you are doing! openHAB is not focused on being exposed to the internet. Sure there is attention to security. But this remains a community driven project, which provides a wide range to powerful ways to access all kinds of hardware and software in your home. So there is no guaranty something can’t be exploited.
Using openHAB cloud it’s not necessary to expose your openHAB to the internet, so that is the recommend why to remotely access your openHAB instance.
To summarize there is no support in openHAB itself to block this. You need to run your own blocking service.
