I am working on establishing vpn from android device using forticlient app with no avail. However, everything works fine with windows 11 machine.

Forticlient app version : 7.4.3
VPN type : IKEV2 (EAP-MSCHAPv2 with Certificate as authmethod)
Android Device: Honor MagicOS 8 (Android version 14)

From the forticlient android, the error immediately shows "IKE authentication failed" where in fortigate debug last log says sent IKE msg (AUTH_RESPONSE).

Appreciated any help on this, thanks

As part of the troubleshooting, can you try without cert authentication? It is useful to try as in case it works then you can focus on the certificate authentication part.

No issue using PSK on the forticlient android app. However, it doesn't support PSK + EAP (username/password) for ikev2 as I need it for remote authentication to windows radius.

Same issue here! No way to make FortiClient for Android works with IPsec IKev2 and Certs authentication. On Windows Machine works fine!

have you found a solution at your side?

Same here.

Can't migrate from ssl vpn to ipsec like that.
