This might be occurring because you are funneling all network traffic through the VPN.
If you are using a Kali VM, we recommend changing the network settings on your VM network interface from NAT to Bridged mode and reconnect to the VPN.
After connecting to the VPN, if you are unable to resolve an external domain name such as www.google.com, we would advise adding the google DNS servers to your DNS resolver file.
For example, on a Kali machine, you can append `nameserver 126.96.36.199` to your /etc/resolv.conf file and then issue the following command: `sudo service networking restart`
Once you have completed this step, you should be able to resolve domains again while connected to the VPN.
