Radius - enterprise WIFI not working

Hi all,

Trying to set up WPA2 EAP with Windows NPS + Unifi WIFI but running into issues that I don't know how to troubleshoot further..

I can't post screenshots so I am going to skip past the setup for now and keep it simple:

-Radius Access request is sent out from the NAS and received on the Radius server

-Radius server replies with Radius Access Challenge

-Request and Challenge are repeated half a dozen times until the client finally reports "Unable to connect to this network" or similar.

Tested with laptop wifi, smart phone, desktop+USB wifi stick. All are the same.

I verified this by taking PCAPS on the firewalls VLAN interface which is connected to the wifi workstation, a PCAP from the Radius server using Wireshark, and a PCAP from the Access point.. The AP itself shows the Radius Access Challenge packet. Is my understanding correct that the radius server is asking for more info (challenge) and not getting it?

Tried to take PCAP from workstation WIFI interface but not able to see any packets.
