Good afternoon!
Can you tell me if anyone has had the same problem? I want to connect to an IKEv2 IPSec VPN that I set up on Mikrotik through the standard Android client, but I can't save the configuration unless I enter the IPSec Identifier.
To be honest, I don't know how to configure it in Mikrotik, and I don't need it, since absolutely all other Windows devices or other Samsung Android phones connect and work fine without entering the IPSec Identifier.
The IKEv2 IPSec VPN on Mikrotik itself is configured for the eap radius authentication method.
