cant ping parrot OS on NAT network

Hello, am new to pentesting and linux genrally, i have a vm running a number of machines(win10&7,kali,parrot and metasploitable) on virtualbox. For some reason i cant ping or establish a connection with all the parrot os but others works fine

probably you want to edit the resolv.conf
or just do
sudo dnstool static 8.8.8.8
