I'm having the same issue: [nmap -sS 10.195.2.2] returns the following-
Starting Nmap 7.40 ( https://nmap.org ) at 2017-06-04 22:10 CDT
Note: Host seems down. If it is really up, but blocking our ping probes, try -Pn
Nmap done: 1 IP address (0 hosts up) scanned in 3.10 seconds
I'm also using Kali Linux with VPN reported as connected by the OS as well as the CTF365 website.
Is the server down for 10.195.2.2?
