Cisco Anyconnect Cannot Establish Connection Secure Gateway



If the DART module was not pushed by the ASA, you would need to download the standalone installer.ISO from cisco.com and execute the anyconnect-dart-win. After that, you should be able to see the Diagnostics option on the anyconnect client. The error message ‘ AnyConnect was not able to establish a connection to the specified secure gateway ’ appears when users try to connect to a VPN using the AnyConnect Client.

I was trying to log into work but had trouble making a VPN connection. I use Cisco AnyConnect VPN Client. This post describes how to fix the following error messages when using Windows 8 Pro:

Gateway
  • AnyConnect was not able to establish a connection to the specified secure gateway. Please try connecting again.
  • The VPN client driver encountered an error. Please restart your computer or device, then try again.

The steps to fix this problem are as follows:

1. Edit a registry entry by running a program called regedit. Right-click on it and Run as administrator. Note that I use Start8, by Stardock, to have a Start button and menu. After you left-click on Run as administrator, your computer might ask you to enter the admin password.

2. Go to the appropriate VPN registry directory called ComputerHKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesvpnva

3. Double left-click the DisplayName key.

An Edit String pop-up window will appear.

The text under the Value data: field on my computer looked like this.

@oem20.inf,%vpnva_Desc%;Cisco AnyConnect VPN Virtual Miniport Adapter for Windows x64

Secure

4. Change the field to

Cisco AnyConnect VPN Virtual Miniport Adapter for Windows x64

by removing all the text and characters that are on the left of the word Cisco.

The end result should look like this:

5. Left-click the ‘OK’ button.

6. Exit the Registry Editor

7. Run Cisco AnyConnect VPN Client and reconnect.

That’s all there is to it. Good luck!

Cisco Anyconnect Cannot Establish Connection Secure Gateway To Router

I recently updated my computer on February 13, 2014 with Microsoft’s updates and saw that the text under the Value data: field on my computer looked like this:

@oem10.inf,%VPNVA64_Desc%;Cisco AnyConnect Secure Mobility Client Virtual Miniport Adapter for Windows x64

It is different from what I had originally posted. I’m not really sure how or why it changed and I don’t have time to find out. I also updated to Cisco AnyConnect Secury Mobility Client Version 3.1.04066. As far as I can tell, the value of …

@oem10.inf,%VPNVA64_Desc%;Cisco AnyConnect Secure Mobility Client Virtual Miniport Adapter for Windows x64

.. works, but the value of

Cisco AnyConnect VPN Virtual Miniport Adapter for Windows x64

Cisco Anyconnect Cannot Establish Connection Secure Gateway

does not work with Cisco AnyConnect Secury Mobility Client Version 3.1.04066.

Changing the Value data: field to

without

seems to work better, too.
