A client on a MAC laptop running Anyconnect client version 4.8.02042 is getting "The VPN connection to the selected secure gateway requires a routable IPv6 physical adapter address. Please move to an IPv6 network and retry the connection or select
a different secure gateway" when client tried connecting to a VPN headend. After a while it seems to connect. We have both IPv4 and IPv6 enabled. I had the client disable IPv6 in the network properties, reboot the MAC and connect and it worked fine. Today with IPv6 disabled, the error message popped up again. Any recommendation, suggestions? This is the only client with this issue, we have hundreds of other client with both MAC and PC connecting successfully using the same version of Anyconnect client.
Thanks in advance.
