Cisco VPN Error 412
The remote peer is no longer responding.
Explanation: This error means that the remote VPN server you are trying to connect to is not responding to your connection.. Usually this means there is a problem with the VPN server, misconfigured, temporary issue, firewall issue, ISP issue, routing, or possibly hardware failure/hung server.
Ping the server if you can, double check the IP/hostname in the connection entry box to ensure it is correct. If hte problem persists, call your helpdesk and see if there are any VPN server issues that the system admins are working on.. or should be working on..
