Can't connect to L2TP VPN

[Tanner1294]

I'm trying to connect to my personal VPN server at home using my Android phone over WiFi but it's not letting me save the L2TP connection? I've typed in all the information except I can't select an IPSec User certificate since there aren't any on the Android. But this shouldn't matter as the server is set to just accept the pre-shared key without any certificates. I can connect with PPTP but there's no internet when I do that.. on L2TP connections there is which is the point of this VPN. Help?
