I'm now facing this problem but I do not try 1hour ago, I'm trying first time in this day I cannot understand what is this problem, why someone using my IP address? Does anyone know that?
https://i.imgur.com/c3J7BTk.pngIt could happen if you claimed too fast or you have more than 1 device which you tried to claim from them.
Did you see any changes in your balance (+42 sats)?
I do not try another device one internet connection and one device only using me, See balance no change but notification is here (not add +42 sats) I want to know that why using my IP another people? Just confused that, are you say about this or know it?

Maybe you are using proxy which is easily available to lots of people.Please use your personal ip address and you sould not see that issue.
