The vpn beta button on the top right hand corner is there for me but I try and turn it on and it says "Couln't connect to VPN. Try again in a few minutes". This continues to happen. I have already went throught the step to turn this feature on with the code that the article refers to and that it is on but it still won't turn on. How do I get this to work. I know it works because when I initionaly it was working but now it doesn't work.
