One setting I would remove is the NAS-IP in the controller configuration for the RADIUS server. The NAS-IP normally has the IP of the controller/switch, not the RADIUS Server. If you leave it empty it will be automatically set.
From this point, I would run a Wireshark on your RADIUS server to see if the RADIUS requests from your controller are reaching the NPS server. If not, you should focus on the controller (or client). If you see the requests, check if there are responses, if not there probably is a problem with the RADIUS Client definition (invalid/non-matching shared secret).
I have very limited experience with NPS, but the experience I have is that if it works it works fine, if it doesn't it's quite hard to get the proper logging to determine where is the problem. Also the configuration is not too intuitive, but that's probably a lack of training in NPS in my side.

Subject: Aruba-VMC Radius Authentication with Windows Server
Hi Everyone, I'm doing my lab about Radius Authentication in Aruba Ap315 managed by Aruba Virtual Mobility Controller and authenticating with Windows Server domain user, I was following guides and documents on the internet but it doesn't work, I don't see any indication that NPS in Windows Server is enabled or configured or connected with Radius client of Aruba-VMC, I also use Event Viewer in Windows Server to view log but there is no log about NPS, I also use AAA server test in Aruba-VMC WebUI to test connect with Radius Server but it just timeout every time, below are all of my configurations about this, anyone can help me to solve this or some document about this. Thank you very much.
