in addition to the existing upgrade host:
Please note that AnyConnect clients with the Roaming security module will not autoupdate unless the setting for cloud update is explicitly enabled in the dashboard. We highly recommend that you turn this feature on, although by default, automatic updates from Cloud Update are disabled. To enable Cloud Updating for Umbrella Roaming Security and the rest of AnyConnect, log into the Umbrella dashboard. Navigate to Identities > Roaming Computers. Under the Settings icon (the gear icon) check "Automatically update AnyConnect, including VPN module, whenever new versions are released. Updates will not occur while VPN is active." For more information about Cloud Updating, please read here.
