I am on 18.04 desktop (ok laptop), and have been successfully using a VPN connection configured using the Cisco AnyConnect VPN (openconnect) protocol. today I received the following error when trying to connect:
Code:
Unexpected 404 result from server
Please upgrade your AnyConnect Client
My questions:
1) what version of the Cisco AnyConnect Client is the openconnect software compatible with in 18.04?
2) Is there a way to force compatablity with a newer version?
3) should I install the Cisco AnyConnect VPN client proper (instead of using openconnect)?

Thanks in advance, please let me know what other info I can provide. I tried to include the log but I cannot copy it through the GUI.
