Unable to get VPN_PROFILE.PS1 to generate VPN

This is on version 1709 using user authentication. Made our template VPN, which connects fine. Ran MakeProfile.ps1 fine and it generated the VPN_Profile.XML and PS1 files. We're use Powershell; VPN_Profile.PS1 looks fine to this untrained eye.

When we run it, locally, as an admin of the machine, running Powershell as admin with execution policy set to bypass, we get this error from the script -

"Unable to create AlwaysOn VPN profile: A general error occurred that is not covered by a more specific error code."

I commented out all of the error catching and found the error is the following line -
$session.CreateInstance($namespaceName, $newInstance, $options)

I looked at each of the variables being passed to the createinstance and all seem fine. Below is their output.

Also including the text of the VPN_PROFILE.PS1 file.

Any thoughts?
