The machine certificate used for IKEv2 validation on the RAS server doesn't have Server Authentication under Enhanced Key Usage. This error typically occurs in one of the following cases: IKE authentication credentials are unacceptable. Ensure that the certificates outlined in this deployment are installed on both the client computer and the VPN server.Įrror description. This error typically occurs when no machine certificate or root machine certificate is present on the VPN server. Contact your network security administrator about installing a valid certificate in the appropriate certificate store. IKE failed to find a valid machine certificate. Ensure that your client configuration matches the conditions that are specified on the NPS server.Įrror description. For example, the NPS may specify the use of a certificate to secure the PEAP connection, but the client is attempting to use EAP-MSCHAPv2.Įvent log 20276 is logged to the event viewer when the RRAS-based VPN server authentication protocol setting doesn't match that of the VPN client computer. The typical cause of this error is that the NPS has specified an authentication condition that the client cannot meet. Please contact the administrator of the RAS server and notify him or her of this error.

Specifically, the authentication method the server used to verify your user name and password may not match the authentication method configured in your connection profile. The connection was prevented because of a policy configured on your RAS/VPN server. Ensure that UDP ports 5 are allowed through all firewalls between the client and the RRAS server.Įrror description. This error is caused by blocked UDP 500 or 4500 ports on the VPN server or the firewall. Please contact your administrator or your service provider to determine which device may be causing the problem. This could be because one of the network devices (e.g., firewalls, NAT, routers) between your computer and the remote server is not configured to allow VPN connections. The network connection between your computer and the VPN server could not be established because the remote server is not responding. The correct certificates for IKE are present on both the client and the server.Įrror description. This error also occurs when the VPN server cannot be reached or the tunnel connection fails. If you know which tunnel to use for your deployment, set the type of VPN to that particular tunnel type on the VPN client side.īy making a VPN connection with a particular tunnel type, your connection will still fail, but it will result in a more tunnel-specific error (for example, 'GRE blocked for PPTP').

This error occurs when the VPN tunnel type is Automatic and the connection attempt fails for all VPN tunnels. If this connection is attempting to use an L2TP/IPsec tunnel, the security parameters required for IPsec negotiation might not be configured properly. The remote connection was not made because the attempted VPN tunnels failed. Error codes Error code: 800Įrror description. For authentication-specific issues, the NPS log on the NPS server can help you determine the source of the problem. For client-side issues and general troubleshooting, the application logs on client computers are invaluable. You can troubleshoot connection issues in several ways. The first step in troubleshooting and testing your VPN connection is understanding the core components of the Always On VPN infrastructure. If your Always On VPN setup is failing to connect clients to your internal network, the cause is likely an invalid VPN certificate, incorrect NPS policies, or issues with the client deployment scripts or in Routing and Remote Access.
