I've recently upgraded to windows 10. Whenever i try to use the VPN, it connects just fine, but won't work. It worked fine on Windows Phone 8.1.
But now the apps that need the VPN to work, aren't working.
(I use L2TP and Cisco AnyConnect)
I am guessing the bug fix will help you. But im the meantime I remember that someone posted in here saying that there was a bug in the vpn settings, saying that you needed to set it up with the protocol as "automatic" for it to work.you should try that. (although my vpn is not set that way and it does work)
