• Ensure you are using HTTPS
• Try disabling IPv6 on your local internet connection
• With Windows occasionally seen issues with TLS being blocked (if you are using Windows)
• Please be sure that your local and corporate firewall allow VPN tunnels
• Another good test (if possible) is to try connecting another PC running a different operating system and see if that one connects
• Go to Network Connections from Control Panel, right-click Cisco AnyConnect Security Mobility Client Connection, and choose Properties. Then disable IPv6, change IPv4 IP settings from Fixed IP to Dynamic. Close all Network Properties dialogue boxes, and try VPN connecting again

Hope this helps
