Hi,
I use AnyConnect 4.10.03314 to log on to several VPN gateways. Yesterday I started to get failed to load preferences for error message and did not get the logon prompt for any of them. Weather I used hostname or full URL for host address in the prompt.
As per the suggestions found online I removed and reinstalled the client. No change.
I removed all the files from C:\ProgramData\Cisco\Cisco AnyConnect Secure Mobility Client\Profile folder and restarted the AnyConnect manager service. Than I entered the URL of the host and got the prompt and progressed through the authentication. But this still does not work for all the VPN gateways.
I have one that prompts me for the credential but that it sys logon failed. When the ISE admin can see the request did not come through to start with.
