The log tells you _exactly_ what the problem is:
> 12[ENC] parsed INFORMATIONAL_V1 request 2090615229 [ HASH N(NO_PROP) ]
> 12[IKE] received NO_PROPOSAL_CHOSEN error notify
The peer doesn't like the crypto proposal sent by the client. So fix
the `esp` setting in the config (maybe you have to enabled PFS by adding
a DH group, ask the other server admin for the correct algorithms).
