Cannot connect to IKEv2 VPN on Win 10 laptop
I set up my IKEv2 Mobile VPN and found a post on Spiceworks (https://community.spiceworks.com/topic/2142945-watchguard-ikev2-mobile-vpn-with-windows-10-failing) that stated that Win 10 cannot connect due to weak default settings. The post recommended running a PowerShell command to fix that issue, which I did (see below).
I use RADIUS with Duo Authentication for my 2FA, and whenever I try to connect, both from an internal computer and from my laptop at Starbucks, it gets to the point of me approving the IKEv2 VPN login in Duo, then comes back with "Can't connect to Hill-T35 IKEv2 VPN" message. SSLVPN works fine with 2FA using Duo.

I cannot get this sucker to work!
