Hello,
Are there any relevant error messages when you perform identity verification?
In addition, the inability to authenticate may also be a version problem. It is recommended that you try to check whether the NPS server and certificate versions are out of date and upgrade or update them accordingly.
For details, you can refer to the link:

Regarding the issue of configuring NPS in AD, you can refer to the link:

Hope this can help you.
Best Regards,
Shujun
