My friend appears online when he shouldn't

Hello everyone, I need some clarification here.

My friends' computer is being switched off however he appears to me as online. I restarted the PC and the Hamachi service just to be sure. What would be the cause for this?

EDIT: I did run a diagnosis and it said something that it can't reach it but when I looked at the properties I did see that there was a speed between the connections.  I would also try to ping but it would say "Time out".

Here is an image with how it looks 😕
