Hi Jakob,

The daemon is not looking for a PSK, but a configuration using PSK
authentication it can use for that client. The lookup is for the local
IP address, the remote IP address and the remote Identity received over
IKE.

A match for that selector is found, but the configuration is not usable,
because it does not allow PSK authentication. The default is public key
authentication. Use authby=psk (or the never leftauth/rightauth options)
to allow PSK authentication on that configuration. man ipsec.conf for
details.

I agree that the log is not very clear in what is wrong here, I'll see
if we can improve that.

Regards
Martin
