[strongSwan] no private key found

Loading the private key has no effect as long as connections are not
associated with a certificate (or raw public key) that matches it.

For ipsec.conf, you have to do that explicitly via leftcert (or
leftsigkey).  With swanctl.conf, certificates may also be loaded
independently and associated to the connection via identity.
