[strongSwan] Galaxy S9 native IKEv2 client tears down connection

That's not exactly what you are doing.  From the server's perspective
you are using a PSK only to authenticate the client (rightauth), the
server is authenticated with a certificate (leftauth, defaults to pubkey
and you also load a certificate).  Maybe the client expects the server
to authenticate with a PSK too, or it doesn't trust the server cert, or
the identity doesn't match.  Anyway, without client log it's difficult
to say what its reason for returning an AUTH_FAILED notify is.
