Hi, my VPN clients suddendly just stopped working. It is not able to establish a Ipsec connection. Turning on debug crypto isakmp gives me this error at the end >>ISAKMP: error, msg not encrypted. What is wrong? I have not changed my config at all. I am running Pix 515 R ver 6.3 and VPN CLient ver 3.6.
