TUNSETIFF failed: Inappropriate ioctl for device

Hello, im using openconnect as vpn. Before 2017-01-03 all builds normal, but after, ive this error when try to connect to vpn.

We do not support using a VPN from within CircleCI [1]. If this ever worked, that is very surprising to me.

The only way to run CircleCI with a VPN is to use the Enterprise Edition [2].
