We have deployed a Firepower Appliance FPR 2110 running ASA 9.8 OS on it. We have created a self signed certificate for VPN connections. After all the necessary configurations for Self signed certificate and Anyconnect VPN on ASA, the anyconnect client is failing to connect. Tested the client on different systems and mobile phone but no luck and same issue. Also note that the 3DES AES encryption license is not enabled on the ASA and there is neither a smartnet contract nor the device is registered on any smart account. However, default ciphers settings for TLS profiles have also been changed to DES-SHA but still the issue persists. Also tried to download the 3DES license from Cisco portal as it doesnt require any smartnet contract but the Cisco doesnt find the provided serial number device( note that show version command serial number has been input on the Cisco portal for license generation). All the certificate signing and Anyconnect SSL VPN configuration along with client error and SSL debugging snapshots have been attached. Any useful response will be appreciated.
