For anyone who is having the same issue, the resolution for me is to set the Extensible Authentication Protocol (EAP) service to Manual and run it. Initially it was disabled and I do not know why as well.
NPS discarded the request EAP-TLS/PEAP
I've setup a new Windows Server 2019 Std as Microsoft NPS server and registered it with Active Directory. My environment is as below:
- One Microsoft NPS server
- Multiple domains (Parent & Child)
- Microsoft NPS server installed in Child domain
- Accounting set to save log file in local host under C:\Logs
I've added all the RADIUS clients (Wireless Controller) into NPS server and configured the network policy to use EAP-TLS and I also tried with PEAP-MS-CHAPv2. When users connect to the Wireless SSID I can see the message in event log as "NPS Server discarded the request for a user". Error code is 1.
I went to configuring Accounting and set the path to local path & unchecked the "If logging fail, discard the request". Unfortunately, NPS server is still discarding the wireless request.

Yes exactly the solution is to set the Extensible Authentication Protocol (EAP) service to Manual and run it.
The Reason Code 1 means that the connection request failed due to a Network Policy Server error.
