I am trying to get a windows client connected to the VPN.
Linux client works just fine with the same configuration, its just the windows

So this uses the default authby= for IKEv2, which does not include rsa-sha1.

168.90.110.44 #1: authentication failed: peer
authentication requires policy RSASIG_v1_5
RSASIG_v1_5 is the RSA variant predating RFC 7427 Signature Authentication.
(well, it is more complicated but that is the essence)
try adding:
authby=rsa-sha2,rsa-sha1
The sha2 variant will use the RFC 7427 variant, and the sha1 variant
will use the legacy RSASIG_v1_5 one. Be sure to test your other clients
that worked before as well.
