The objective of this document is to show you basic troubleshooting steps on some common errors on the Cisco AnyConnect Secure Mobility Client. When installing the Cisco AnyConnect Secure Mobility Client, errors may occur and troubleshooting may be needed for a successful setup.
Cisco Defense Orchestrator (CDO) is a cloud-based, multi-device manager that manages security products like Adaptive Security Appliance (ASA), Firepower Threat Defense next-generation firewall, and Meraki devices, to name a few. We make improvement. View more ISE Data limiting best practices Created by Jonathan Casillas on 04:34 PM. Associating a DHCP Pool for AnyConnect Clients (SVC) 7 posts. I did some research online to try and validate this and in the 'Cisco ASA 5500 SSL VPN Deployment Guide, Version 8.x', it instructs.
Note that the errors discussed in this document is not an exhaustive list and varies with the configuration of the device used.

Basic Troubleshooting on Cisco AnyConnect Secure Mobility Client Errors
Note: Before attempting to troubleshoot, it is recommended to gather some important information first about your system that might be needed during the troubleshooting process. To learn how, click here.
1. Problem: Network Access Manager fails to recognize your wired adapter.
Solution: Try unplugging your network cable and reinserting it. If this does not work, you may have a link issue. The Network Access Manager may not be able to determine the correct link state of your adapter. Check the Connection Properties of your Network Interface Card (NIC) driver. You may have a 'Wait for Link' option in the Advanced Panel. When the setting is On, the wired NIC driver initialization code waits for auto negotiation to complete and then determines if a link is present.
2. Problem: When AnyConnect attempts to establish a connection, it authenticates successfully and builds the Secure Socket Layer (SSL)session, but then the AnyConnect client crashes in the vpndownloader if using Label-Switched Path (LSP) or NOD32 Antivirus.
Solution: Remove the Internet Monitor component in version 2.7 and upgrade to version 3.0 of ESET NOD32 AV.
3. Problem: If you are using an AT&T Dialer, the client operating system sometimes experiences a blue screen, which causes the creation of a mini dump file.
Solution: Upgrade to the latest 7.6.2 AT&T Global Network Client.
4. Problem: When using McAfee Firewall 5, a User Datagram Protocol (UDP)Datagram Transport Layer Security (DTLS) connection cannot be established.
Solution: In the McAfee Firewall central console, choose Advanced Tasks > Advanced options and Logging and uncheck the Block incoming fragments automatically check box in McAfee Firewall.
5. Problem: The connection fails due to lack of credentials.
Solution: The third-party load balancer has no insight into the load on the Adaptive Security Appliance (ASA) devices. Because the load balance functionality in the ASA is intelligent enough to evenly distribute the VPN load across the devices, using the internal ASA load balancing instead is recommended.
6. Problem: The AnyConnect client fails to download and produces the following error message:
Solution: Upload the patch update to version 1.2.1.38 to resolve all dll issues.

7. Problem: If you are using Bonjour Printing Services, the AnyConnect event logs indicate a failure to identify the IP forwarding table.
Solution: Disable the Bonjour Printing Service by typing net stop “bonjour service” at the command prompt. A new version of mDNSResponder (1.0.5.11) has been produced by Apple. To resolve this issue, a new version of Bonjour is bundled with iTunes and made available as a separate download from the Apple web site.
8. Problem: An error indicates that the version of TUN or network tunnel is already installed on this system and is incompatible with the AnyConnect client.
Solution: Uninstall the Viscosity OpenVPN Client.
9. Problem: If a Label-Switched Path (LSP) module is present on the client, a Winsock catalog conflict may occur.
Solution: Uninstall the LSP module.

10. Problem: If you are connecting with a Digital Subscriber Line (DSL) router, DTLS traffic may fail even if successfully negotiated.
Solution: Connect to a Linksys router with factory settings. This setting allows a stable DTLS session and no interruption in pings. Add a rule to allow DTLS return traffic.
11. Problem: When using AnyConnect on some Virtual Machine Network Service devices, performance issues have resulted.
Solution: Uncheck the binding for all IM devices within the AnyConnect virtual adapter. The application dsagent.exe resides in C:WindowsSystemdgagent. Although it does not appear in the process list, you can see it by opening sockets with TCPview (sysinternals). When you terminate this process, normal operation of AnyConnect returns.
12. Problem: You receive an “Unable to Proceed, Cannot Connect to the VPN Service” message. The VPN service for AnyConnect is not running.
Solution: Determine if another application conflicted with the service by going to the Windows Administration Tools then make sure that the Cisco AnyConnect VPN Agent is not running. If it is running and the error message still appears, another VPN application on the workstation may need to be disabled or even uninstalled. After taking that action, reboot, and repeat this step.
13. Problem: When Kaspersky 6.0.3 is installed (even if disabled), AnyConnect connections to the ASA fail right after CSTP state = CONNECTED. The following message appears:
Solution: Uninstall Kaspersky and refer to their forums for additional updates.

14. Problem: If you are using Routing and Remote Access Service (RRAS), the following termination error is returned to the event log when AnyConnect attempts to establish a connection to the host device:
Solution: Disable the RRAS service.
15. Problem: If you are using a EVDO wireless card and Venturi driver while a client disconnect occurred, the event log reports the following:
Solutions:
- Check the Application, System, and AnyConnect event logs for a relating disconnect event and determine if a NIC card reset was applied at the same time.
- Ensure that the Venturi driver is up to date. Disable Use Rules Engine in the 6.7 version of the AT&T Communications Manager.

Get Cisco AnyConnect - 8 Great Secure VPN Alternatives
I use Cisco AnyConnect on my Windows 7 computer to make VPN connections. It also has capability to connect to WiFi. But I always had problems in connecting toWiFi with AnyConnect. Connection drops frequently and it keeps saying ‘Acquiring IP address‘.
Cisco Anyconnect Keeps Associating
AnyConnect installs a service called ‘Network Access Manager‘ which seems like takes over the native Windows WiFi connecting client. So when I click on the network icon in the System tray it says ‘No connections are available'(See below snapshot). Without AnyConnect, it always displays the WiFi connections available.
If you are facing the problem then you can try the following solution that worked for me.
- Open Services management console by running Services.msc from Run
- Find the service ‘Cisco AnyConnect Network Access Manager‘.
- Right click and stop the service.
- Now Cisco AnyConnect will say ‘NAM service unavailable‘
- Now Windows will use the native WiFi client to connect to the WiFi
- When you reboot your system, the NAM service will start and may cause problem again. You can disable this service in Services management console to prevent that.
AnyConnect has settings to disable the NAM feature. But that did not work for me. Even after disabling NAM service, I could not connect to WiFi. Windows network icon shows the WiFi connection but gives the error ‘Windows was not able to connect to…‘. I followed the below steps to do this.
- Opened Anyconnect window and click on Advanced.
- Clicked on ‘Networks’ tab in the left side pane.
- Clicked on Configuration tab. Changed the NAM to disabled as shown below.
