Hello!
Recently I have not been able to connect to my work VPN server from my iPhone or iPad on AT&T's LTE or 4G network - it seems to be due to proxy configuration on AT&Ts network perhaps?
As soon as my iPad mini or iPhone are placed on WiFi I can connect without issue. The VPN server odly enough is on AT&Ts network.
I can connect on any WiFi network whether it be at home (TWC Internet) or a co-workers house (WOW) but AT&T's network is a no go. I also have VZW on my iPad Air and VPN works fine on VZWs LTE netowrk.
Any ideas what chnaged and what can be done to resolve?
