During validation attempts,from an Eguardpost VPN device, the following error may occur during initial attempts:

 
ERROR    "2013-04-29 13:33:39.748 GMT-0500"  192.168.101.240 ValidationEngine 0 18480 "text=[VSWebServiceClient] Unknown Error [12: An exception raised by the service]!, user=username, bizCont=off" Thread-1628 VSValidationEngine.c

Use the VSradius test tool to ensure that validation attempts are successful. If they are not, then further configuration of the Enterprise Gateway is necessary.

If VSradius tests are successful,  then ensure that he shared secret on the validation server matches what's used on the VPN device.
