Dec 29, 2012 Hi, Its been a while since I first wrote the article. I’m currently using Windows 10 Pro, 64-bit on a Microsoft Surface Pro 3. The version of the Cisco AnyConnect Secure Mobility Client is 3.1.12020.

In the Windows Control Panel navigate to Internet options (Network and Internet Connections, and then Internet Options)

Once there, the user will need to select the Connections tab, and then LAN Settings. Make sure the option 'Use automatic configure script' is unchecked, reboot, and then retry Cisco AnyConnect.

In general, don’t upgrade a system until all prerequisites are available. If you’re not sure or just in general, perform a test install and a scratch upgrade. As for this app, check for an update, and then contact Cisco Support if not.

Cisco AnyConnect Users With macOS 10.15 Might Not Be Able To Establish VPN Connection or Might Receive System Pop-up Messages—Software Upgrade Recommended

Quick Fix: VPN Session Ended Cisco AnyConnect Secure Mobility ..

Cisco AnyConnect and HostScan require updated releases for compatibility with the upcoming macOS Catalina release (10.15). Beginning with macOS Catalina release (10.15), the operating system will no longer support the executing of 32-bit binaries. Additionally, applications must be cryptographically notarized in order to be installed by the operating system. Cisco AnyConnect 4.8.00175 is the first version that officially supports operation on macOS Catalina and contains no 32-bit code.


Which implies there’s a bug or mis-configuration here. If there’s no newer AnyConnect version and no other support notes, contact Cisco Support. This is a Cisco app, so Cisco Support will have a better position to identify and address any app issues.
