9:22:40 AM AnyConnect was not able to establish a connection to the specified secure gateway. Please try connecting again.
A simple solution for Cisco Anyconnect Secure Mobility Client issue is to click on the menu icon near Network and check "Connect only to Current Network". This will allow the connection to stay in the specified/desired Wifi and will stop from fluctuating to "wired" connection. (Cisco version :4.4.03034 System : Windows 10 version 1709)
