I have been seeing much more traffic shaping on the internet then ever
before, and it frequently breaks things like VPN. Since it worked, and
failed, I would get your ISP support on the line and start them working
on why they broke your application. I have found them surprisingly
responsive. I think they know that the traffic shaping is breaking more
things then they intend...
