Hello everyone,
i`m trying to set up a VPN tunnel with the native Android 13 (Grapheneos) VPN Client. The connection comes up and goes down directly.
IKE Dubug Output:

I hope that someone can help me.
Thanks in advanced.

Hi @AIXNET
I verified the ike debugs you have shared, I can see the dynamic tunnel was created for 80.187.102.50

As it is dial-up connection so mode-config is enabled, and the DNS details and IP details are pushed as per the debugs.
But once the tunnel is established, post to the SNMP trap for the tunnel to be up. When FGT sends the AUTH response and it receives a new informational message with the peer to delete the SA kindly find the logs below :

Hi @asengar,
thanks for your reply.
The question is why the client is sending the delete request. In Android 13 you can only configure the VPN type (IKEv2/IPSec PSK), server address, ipsec id and the PSK.
I configured the VPN tunnel with the same settings on a LANCOM router and its working properly. It seems to me that the Fortigate send something in the AUTH_Response what the client is unable to handle with.
Any further ideas what i can do (traces etc.) to locate the problem?
Thanks in advanced
