The "Certificate Validation Failure" error occurs when an obsolete XML profile is deployed on the connecting client. To remove this error, manually erase the XML profile from the computer and restart the Cisco AnyConnect VPN client. The location of the XML profile varies on the operating system, see below:
|Operating system||Profile location|
|Windows XP||%ALLUSERSPROFILE%\Application Data\Cisco\Cisco AnyConnect Secure Mobility Client\Profile|
|Windows 7||%ProgramData%\Cisco\Cisco AnyConnect Secure Mobility Client\Profile|
|Windows Vista||%ProgramData%\Cisco\Cisco AnyConnect Secure Mobility Client\Profile|
The "Certificate enrollment failed." error occurs when the Cisco AnyConnect Client fails to enroll for a certificate on behalf of the user.
If you get this error, please contact DPDHL IT Services through your local DPDHL contact providing your username.
If the Cisco AnyConnect Client is stuck at the step shown above for a few minutes without any progress, it means that the client is unable to obtain and download the certificate.
If you get this error, first close AnyConnect client and start it again (right-click on the AnyConnect icon in the taskbar and click :Quit".
After restarting AnyConnect, if the same problem presist, please contact DPDHL IT Services through your local DPDHL contact providing your username.
The Cisco AnyConnect VPN client comes with a DART module (Diagnostics and Reporting Tool) used to collect client and system data when resolving connection issues. To access DART interface, click on the highlighted icon in the Cisco AnyConnect connection window, see below:
The DART packs the collected data into a .ZIP archive and stores it at the user's desktop.
In case of problems with vpnagentd service (service is marked as down or hangs), is usually not enough just to start it, but due some dependeces to stop it first. So even it looks not running, stop it first, then start and then check status.
/opt/cisco/anyconnect/bin$ systemctl stop vpnagentd
/opt/cisco/anyconnect/bin$ systemctl start vpnagentd
/opt/cisco/anyconnect/bin$ systemctl status vpnagentd
Symptoms of this issue are, that VPN client can't fully start in CLI or GUI (it hangs) - see Step 6 in Linux installation guide. This was seen at Ubuntu 16.04 LTS, usually after certificate was imported.
GUI client works well at Ubuntu 16.04, but not at Ubuntu 18.04.1; for Ubuntu 18.04.1, use only CLI part of client.
Syslog log file is good source to observe, what is happening behind ...
Note, that in GUI version of client is no information messages like can be seen at screen during operating CLI version of client, so if you need get more info, use CLI version and syslog file to observe what is going on...
According our testing, it is not possible to use OpenConnect VPN client.
Tested was OpenConnect 7.06-2build2 on Ubuntu 16.04. It looks, that OpenClient is not capable to utilise our key feature - Autoenrolment of certificate. It seems, that only way, how to add user certificate into client, is manual import of .cer and .key (cert + key) files. In this case You are not able to obtain certificate automatically, how DHL VPN service is configured now.
Unfortunately Cisco does not support Windows XP and similar obsolete Win"X" systems anymore.
Users with Windows XP needs to upgrade to Windows 7/8/10.
