ClearPass Error 215

A workstation was joined to the domain. It was ypgraded from Win 7 to Win 10 and now ClearPass gives me this error: 

EAP-PEAP: fatal alert by client - unknown_ca
eap-tls: Error in establishing TLS session

802.1x is configured on the switchport.

I'm thinking something changed because of the upgrade and now ClearPass won't authenticate because it thinks it's a different workstation?

I removed aaa config off port, bounced it, then reapplied aaa config. 

ClearPass still won't authenticate it? 

Any suggestions?

Re: ClearPass Error 215

Is your EAP server certificate public or privately signed?

 

Are your supplicants configured via group policy or manually?

Re: ClearPass Error 215

I removed the computer from the domain, deleted the computer account in AD, then rejoined the domain and everything came up smoothly.
