IPSec Mobile Client VPN will not connect

[blainer]

OPNsense 15.7.18_1-amd64
FreeBSD 10.1-RELEASE-p23
OpenSSL 1.0.2d 9 Jul 2015

I have tried almost every possible combination of settings and I CANNOT produce a working IPSec VPN connection, with either my Android phone or ShewSoft VPN Client on Linux or Windows.

I always hit the same two errors and cannot for the life of me figure out how to solve either.

When trying Hybrid RSA + Xauth this is the result.

When trying Hybrid PSK + Xauth  I get reconnecting errors until it times out and deletes the half open IKE session.

I have followed the guides word for word, still unable to get this working.

Please help.
