RUTX50 IKEv2/IPSec PSK not working

Hi, I have a problem connecting Android phones to RUTX50.
The problem is exactly the same as in this thread https://community.teltonika.lt/t/android-14-vpn-ipsec-rutx50-not-working/3038. Has anyone managed to connect?
Configuration exactly as from https://wiki.teltonika-networks.com/view/Setting_up_an_IPsec_tunnel_between_RUT_and_Android_phone
Public IP address on the router side. Last firmware RUTX_R_00.07.12
