Authentication issue when trying to login to WiFi using NPS server.

Question

Recently there has been an issue with a computer connecting to wifi at my company coming back with a message of "can not connect". We are in an environment using RADIUS via NPS to authenticate users. The logs on the NPS are telling that there is a credential mismatch, but there have been multiple users that have tried their credentials to the wifi but no luck on that certain device. Then I get check the logs on the computer where there are two logs that generate, one saying a credential mismatch and the other saying "the authentication failed because the certificate on the server computer does not have a server name specified.

I have done all the basic troubleshooting on the computer such as resetting network settings, manually connecting wifi with encryption methods and such, changing bands but still a "can not connect."

I know the log talks about a certificate issue on NPS but other computers and users are able to get to the wifi. Only this device and maybe a couple other have this issue. I can provide more details, but any ideas on what I can check to resolve issue on either NPS or computer?
