Issue loading OpenVPN external site when proxied

So I guess I hit a bit of a moot point here.

Looks like proxying the VPN domain causes the VPN to not work.

So it looks like I will have to use DNS only. Now I need to find out how to get a cert that will work for a non-proxy site from cloudflare.
