NPS Event 6723 Code 8

I receive this event twice in the NPAS event viewer:

Note:

1. User MararoD is in a security group granted access as a Condition in the Network Policy.
2. Certificate has successfully been auto-enrolled to the above user and valid.
3. PEAP is the Authentication Method.

I've posted this question 3 times and still no help.

So, please, anyone, HELP!!
