When connected to the VPN using Cyberghost in Ubuntu, if the computer is turned off and then on again, the internet connectivity faces some issues. To fix it:
sudo ip link set wlp3s0 down sudo ip addr flush wlp3s0 sudo ip link set wlp3s0 up sudo dhclient -r sudo dhclient
For “wlp3s0” use your internet adapter name
The best way to avoid this from happening is to run the below command before you turn off your computer.
sudo cyberghostvpn --stop
