Hello,
Can you access both CAM (Manager) and CAS (Server) and verify that the Clean Access Agent is on the appropriate location on both?
You need to download WinSCP and access the devices that way. Check the CAM under:
root/perfigo/control/data/upload
Check on the CAS as well and verify that the appropriate file is in there:
/perfigo/access/tomcat/webapps/auth
The appropriate file should in there. Also, I have seem that error message when the CAS has a Wildard (*) certificate installed on it. NOTE: Remember that Wildcard Certificates are no supported on NAC deployments.
Hope this helps.
Regards.
