I have been unable to connect using Mac OSX VPN Client 4.9. The message "DEL_REASON_PEER_NOT_RESPONDING" continues to show up. Attached is the log.
Do you see the connection requests on the VPN Server. Based upon the logs, looks like the IKE packets are never making to the client. Could be a firewall on the client side that is blocking IKE/IPSEC Traffic or the VPN server itself not responding. If this is the only client having issue, then check for any personal firewall or Firewall device blocking traffic.
*Pls rate if it helps*
