AON VPN Failed in W 10.0.19042 enterprise

Question

I have the following problem, I am implementing AON VPN with the following Servers:
* NPS / Radius
* VPN / RRAS
The test laptop is a Windows 10.0.19042 Enterprise.

I do the steps indicated in the manuals and when I make the VPN Template for the first time and try to make the connection, it sends me the error code 860, having the VPN connection type in Automatic mode.
If I change it to IKEv2 it sends me error code 812.

Ideally, it should work with IKEv2 since this is how it is configured on servers with EAP and authentication is through certificates.

I have more than a week reviewing the possible failures and possible solutions but I cannot complete the connection, someone who can guide me.

Hello, DanielMeza,

I assume this is the error message you are getting: "The remote access connection completed, but authentication failed because of an error in the certificate that the client uses to authenticate the server."

As you said you are using an IKEv2 VPN connection on your Windows PC (and you've probably created that connection manually). To resolve this issue, make sure to open the Settings app and navigate to your VPN connections. Then, click on 'Change Adapter Settings' and right-click on the VPN connection that's failing to connect. Select Properties > Networks and untick 'Internet Protocol Version 6,' 'File and Printer Sharing,' and 'Client for Microsoft Windows.' Also, right-click on 'Internet Protocol Version 4' and select Properties. Make sure to check 'Use default gateway on remote network' box.
