Hi,
First please make sure that the username and password are correct. Do not forget to add the domain name after the username. Normally, it should like
username@yourdomain.com or YOURDOMAIN\username.
Please check if the NPS server has been registered in the domain controller. To verify this, please check if the NPS server has been added into the
RAS and IAS Servers group in the domain controller.
If issue persists, please provide the detailed configuration of your Network Policy. It may give some hints.
Best Regards.
