TLS v1.0 protocol communications from App Volumes agents is disabled. All communication from the agent is done through TLS v1.1 and TLS v1.2 protocols.
App Volumes Manager can communicate with older agents only if the Allow TLS v1.0 protocol (Not recommended) box is selected. This box is deselected by default.
You can enable TLS v 1.0 support for App Volumes Manager during App Volumes Manager installation. Select the Allow TLS v1.0 protocol (Not recommended) box when you install App Volumes Manager. See the Install App Volumes Manager section in the App Volumes Installation Guide.
