Hi Ricardo,
Can you please confirm if you are using any older hostscan version or perhaps older hostscan package present on ASA?
From
https://www.cisco.com/c/en/us/td/docs/security/asa/compatibility/asa-vpn-compatibility.html#id_64187"We always recommend that you upgrade to the latest HostScan engine version. AnyConnect will not establish a VPN connection when used with an incompatible version of HostScan. Ensure that you are running the version of HostScan that is the same version as AnyConnect. "
Regards,
Dinesh Moudgil
