Description (partial)

Symptom:
After successful ASA web-deploy upgrade from AnyConnect 4.8.01090+ to any other AnyConnect 4.8.x build on Windows, AnyConnect shows following message:

The secure gateway has rejected the connection attempt. A new connection attempt to the same or another secure gateway is needed, which requires re-authentication.
The following message was received from the secure gateway: Other error

Conditions:
AnyConnect 4.8.01090+ for Windows connecting to an ASA that has a 4.8.x configured for auto update (web-deploy).

The error popup will only occur if a VPN connection was established within the current Windows boot session prior to establishing the VPN connection that triggers the auto update.

The ASA must contain the fix for CSCvq73599.
