You do not have a subjectAltName=178.197.x.x in our certificate as a valid ID.
The IKE ID has to match a subjectAltName= to prevent another certificate
that is valid, but or a different ID, to spood this IKE ID. Since many
people have generated bad certificates, we provide the override option.

What is your authby= line? Perhaps try authby=rsa-sha1 ? It looks like
it is trying rsa-sha1 but the remote peer does not support that and is
(against RFC 8472) trying to use rsa-sha1 with the RFC 7427 method.
