Improve UI on vpn fail close
If the VPN gets disconnected bitmask will fail close (keep the firewall blocking all internet traffic). The UI handles it correctly showing two buttons Turn ON
(maybe we should rename it to reconnect
?) and Unblock
.
But there is no description of the situation of to user, it just says VPN Failed
. Let's add some description of what fail close is and what are the meaningful options for the user.
