From the 2nd of April 2017 you may have had trouble connecting to VPN. If you get the warning "Untrusted VPN Server Blocked!" (red background", do the following:
- Click "Change Setting..."
- Un-check "Block connections to untrusted servers" in the next window
When you try to connect next time, you will get a "Security Warning: Untrusted VPN Server Certificate"-warning. Chose "Connect Anyway".
