VPN Verifying Username and Password

Question

I have defined a VPN connection and selected the following security items:
IKEv2
Authentication using machine certificates (NO userID and Password' NO EAP)
Yet when I try to connect the first connection message that pops up is " Verifying Username and Password "
That sits there a few seconds
Then the next message is "Verifying Username and Password "
                                      "error 13819  Invalid
Certificate Type"
WHY is the process trying to verify a user name and password when I've done the following:
Defining the VPN connection I DID NOT enter a userid and password, I left these fields blank.
I also DID NOT select EAP authentication (I'm using IKEv2)
I selected machine certificates.
Is there a problem with the windows VPN logic?

Hi 2UCowpoke,
For machine certificate connection require moving/installing the certificate to the machine store. it is possibly due to either the client not having a
certificate or the server certificate is incorrect.
I found similar case on TechNet for your reference

Since questions in your reply is related to Windows Server certificate, I’d suggest that we post at
Windows Server Security forum. There you can get more effective suggestion by other experts who familiar with design of certificate. Your understanding is highly appreciated.
