IPSec vpn with certificate on android

[abdelkarim.yousef]

Hi,

I configured VPN Client IPSec with sertificate (RSA) authentication on ASA 5520 8.3.

i requested certificates from MS CA by entering URL: http://serverIP/certsrv and request the certificate and install it on the client

the configuration worked fine on cisco vpn client installed on a computer, but when i establish the VPN on android device (IPSec Xauth RSA) on version 4.4.2 it gives me the following error:

IKEv1: received encrypted Oakley Informational packet with invalid payloads

Can you help me

I would upgrade the ASA 5520 to asa847-30-k8.bin first.

Have you considered using the certificate authority built into the ASA?

I upgraded it to Cisco Adaptive Security Appliance Software Version 8.4(7)30

I still have a problem, below is what i get when i enable debug on ipsec and ca and connect from android device:
