I have been using my VPN connection successfully for a few months on v 18.04. Openconnect reports its version as v7.08-3ubuntu0.18.04.1
Recently when I have tried to establish a connection, I have been getting a message from the server that I need to upgrade the version of my Cisco AnyConnect:
Please upgrade your AnyConnect Client
Failed to obtain WebVPN cookie
My question: how do I know what version they are expecting, and what version of Cisco AnyConnect does this version of Openconnect support/emulate?
FWIW - I have the Windows version of Cisco AnyConnect running in a VM, it is reporting as 4.7, and it still connects without a problem.
