Phase-two Quick Mode failure occurs due to configuration/misconfiguration of VPN/encryption domain for firewalls involved in Site-to-Site VPN tunnels. Typically, this occurs when VPN domain group contains either numerous networks, or numerous hosts from different consecutive networks along with network objects.
