Setting up IPSec on Android

[Niknok]

Hello,

I'm having trouble setting the VPN up on my Android phone. It says that its connected but when I try to go to a website, it says "[website]'s server DNS address could not be found".

Here is a screenshot of what I've entered for the VPN profile:

Android version: 6.0.1

So, I've just tried to use the app but it always says "Failed to establish VPN: Gateway is unreachable". I'm using the VPN while connected to my WiFi (I can't access the mobile-network where I currently am) but when I use the VPN on my Computer (same network) it works just fine.
