Issue connecting to NPs from WLC

[vban]

Hello,

This is the error message when I try to test my RADIUS server

Attempting authentication test to server-group SERVERS using RADIUS
 user authentication request was rejected by the server.

  - @vban     1) Verify if the shared secret is correctly configured on the WLC
                    2) Check the NPS radius logs for the authentication request from the configured test user,

Its correctly configured. We are using windows 2K22 server, i have manually generated the key and entered in WLC and server. But it's still showing me the same error.

This message is from server Event logs,  A RADIUS message was received from the invalid RADIUS client IP address x.x.x.x.

From wlc make sure you select correct vlan interface (mgmt interface) 

In NPS make sure you add this IP as NAD
