I have a single AnyConnect user who has reported random disconnects so I have gone through all the checks I can make and looking at the logs I see the reason for the disconnect appears to be 'Loss of the network interface used for the VPN connection.' which is Reason code 8 by the looks of it.
Firstly is there a list of codes and explanations of the reasons or does anyone know what would cause a Reason 8 - loss of the network interface used for VPN connection and what it means.
Is this a loss of connection via WiFi maybe or is this an application level issue? It would be handy to know so I can either say get your home WiFi sorted or do I maybe need to re-install or upgrade the client.
Does anyone have an idea what the cause is?
Client version - 4.4.00243
