Android 13/IPAD IOS 15.7 and USG40 with IKEv2

Options
Hi,

I have used earlier L2TP/IPSEC tunneling but now newer andoids doesn't support that one. 

I did IKEv2 configuration according these.
https://support.zyxel.eu/hc/en-us/articles/8805317185298-VPN-Configure-IKEv2-with-Pre-Shared-key-on-Mobile-Devices-Instead-of-L2TP-


When I try make a connection I will get always error message in both devices android (SAMSUNG S20) and IPAD.

Any Ideas? KR,J
