Windows basics - can't connect to any ip

I am doing the windows fundamental module, but when I try to generate an IP to connect to do the exercises, there is no connection. I try to ping from the attack box without succeed. I have doing modules for a certain time without this problem. Do you guys have any experience with this?

are you doing it in your VM?

No, i’m using the parrot htb machine.

maybe try again sometimes that helps
