Basic Troubleshooting on Cisco AnyConnect Secure Mobility Client Errors
1. Problem: Network Access Manager fails to recognise 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: 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.
4. 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.
5. Problem: The AnyConnect client fails to download and produces the following error message:
Solution: Upload the patch update to version 220.127.116.11 to resolve all dll issues.
6. 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 (18.104.22.168) 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.
7. Problem: If a Label-Switched Path (LSP) module is present on the client, a Winsock catalogue conflict may occur.
Solution: Uninstall the LSP module.
8. 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.
9. 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.
