Looks like Aruba's VIA VPN iOS app is broken on T-mobile's USA network. Before I open a ticket I want to see if anyone else can confirm this.
I can download the VPN profiles on my devices, but the connection fails right away, pretty much it is not even trying to connect, no time outs mentioned just says disconnected right away. The logs on my controller only show a profile download attempt on 443, once the profile is downloaded I don't see any other connection attempts on the controller, nor do I see any hits on our boarder router.
Other VPN's I have tried work (SecurePulse) on T-Mobile. Other carriers also work with VIA (Verizon, Sprint), so it is not the configuration. I think this is related to some IPV6 changes on T-mobile's side that VIA doesn't know how to handle.
