This document describes a scenario where user receives a message when Anyconnect fails to connect.
The following message is displayed during a failed anyconnect attempt:
"The server certificate received or its chain does not comply with FIPS. A VPN Connection will not be established"
You may want to check the Anyconnect Local Policy on the affected machine.
The AnyConnectLocalPolicy.xml can be found in the following directory on Windows XP:
C:\Documents and Settings\All Users\Application Data\Cisco\Cisco AnyConnect VPN Client
For Windows 7 or Vista:
C:\ProgramData\Cisco\Cisco AnyConnect VPN Client Edit the 'AnyConnectLocalPolicy.xml' file so that the Fips Mode is set to false: e.g. <FipsMode>false</FipsMode> Save the changes and launch another anyconnect session. A reboot of the PC may be necessary in some cases.
