[strongSwan] Issues with StrongSwan Android client and Azure MFA

So I have tried excluding Microsoft Authenticator from the VPN (with the
advanced settings), but I get the same result. On a whim I tried allowing
only Chrome to use the VPN. That allowed me to connect, but from Chrome I
couldn't get to any internal websites. Plus that really wouldn't be a
feasible solution as people are going to want to use many different (and
unknown to me) apps on the VPN. Is there another Android subsystem that
needs access as well besides the authenticator? The other piece that
complicates this is the MFA challenge comes from Azure, so I don't have a
simple network list to exclude from the tunnel.

I will keep looking.....
