Cisco Cisco AnyConnect Secure Mobility Client v2.x Troubleshooting Guide

A security threat has been detected in the received server certificate. A VPN 

connection will not be established.

A security threat was detected in the received server certificate. The threat is likely the 

result of a null character prefix attack.

Report the issue to your organization's technical support.

Provide instructions to obtain the certificate required for VPN 

access.

A user other than the one who started the VPN connection has logged into the 

computer locally. The VPN connection has been disconnected. Close all sensitive 

networked applications.

AnyConnect disconnected from the VPN because another user logged into the local 

console, the AnyConnect client profile Retain VPN on Logoff parameter is enabled, and the 
associated User Enforcement parameter is set to “Same user only.” Thus, the client is configured to 
retain the VPN connection following the logoff of the local console user, and to disconnect from the 
VPN if a different user logs into the local console. The different user was not authenticated by the 
secure gateway for access to the private network, so the VPN connection has been disconnected to 
ensure the protection of the private network.

Ask the unauthenticated user to log off, then try a new VPN connection.

Account expired.

Message originated from the Cisco ASA. The ASA rejected the VPN access request 

because your account is locked or expired.
