Azure VPN Client not working:Server did not respond properly to VPN Control Packets

Project: I have created a VPN GW in Azure. A p2S vpn GW is working when connecting using a Mac. With my Mac, I am connecting using a child certificate and the VPN client in the networking settings. The RootCA certificate is correctly installed in Azure vpn gw. We are using certificate authentication - not Active Directory.

My Goal My goal is to make the windows client work with the Azure VPM GW as a p2s client (same as my Mac - which works flawlessly).

The Problem

For windows, I install the client certificate; but the the VPN connection does not work when using either the Azure VPN Client or the OpenVPN client.

The Question: Do I need to add/install the Azure VPN Client app in Enterprise Applications, within Azure AD, to use the azure vpn client? What about the OpenVPN App?

I noticed that in the Azure Tenant the Azure VPN Client app isn't installed as an Enterprise App.

The Error Messages:

Do you have the root certificate’s public key installed locally on the Windows client?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
