I'm having the same problem today, and it started after I installed software updates on my Mac.

I'm also having this problem. Haven't had the VPN for long. It begins connecting for a few seconds then says "Disconnecting - Unmasking connection and location."

I also recently left my laptop asleep and when I came back to it the VPN was on and had been running for hours. Turned it off, then tried to turn it on again, back to this same issue.
