No Certificate for EAP-TLS ISE ver1.2

[Admin Eastland]

                   I keep getting these errors each time.

Failure Reason=No session found as part of challenge password 0a800c19000024485238a83c:9dc484fa-28c5-472b-ae3d-0d347747a8b6

Failure Reason=Certificate provisioning complete. Duplicate certificate request by CN=jdoe

Any idea? The Network Setup assistant fails with "failed to install identity certificate error code [1006]

I don't know what it's trying to tell me?

Thanks for any help

Refresh your Cisco ISE trusted certificate.

This issue can also arise if the Cisco ISE FQDN2 changes and/or the name of the

certificate imported on the client machine has changed

The supplicant or client machine is not accepting the certificate from Cisco ISE.

The client machine may be  configured to validate the server certificate, but is not

configured to trust the Cisco ISE certificate.
