Error: "Connection Attempt Failed"

Post by Theet »

This error message implies that if you want to use the Always-On feature, you need a valid sever certificate configured on the headend. Without a valid server certificate, this feature does not work. Strict Cert Mode is an option that you set in the AnyConnect local policy file in order to ensure the connections use a valid certificate. If you enable this option in the policy file and connect with a bogus certificate, the connection fails.
