Fedora has obsoleted openswan and replaced it with libreswan. If you run
a yum update it should update your old openswan to the latest libreswan.

Your private key in /etc/ipsec.secrets (or via include files) is not
being used. It has to be generated from within the secure NSS store.

run this:

ipsec stop (if already running)
rm /etc/ipsec.d/*db   (if running libreswan < 3.6-2 and it has been started once)
ipsec initnss         *if running libreswan < 3.6-2 and it has been started once)
ipsec newhostkey --output /etc/ipsec.d/hostkey.secrets --configdir /etc/ipsec.d

Then run "ipsec showhostkey --left" to get your new public raw RSA key.

Also change authby to be just: authby=rsasigkey
