Fortiauthenticator Radius setting with Windows 10 client

Hi All,

Having issue connecting Windows 10 to FortiAp with WPA2 Enterprise setting. Was previously connecting with no issue, but was unable to connect starting this week. Below would be the testing I have done.

Design:

FortiAP -> FortiGate -> FortiAuthenticator -> AD server

Testing Done:

1. Windows 7 client to SSID (No Issue)

2. Android/Apple device connecting to SSID (No Issue)

3. Windows 10 connecting to SSID (Issue)

Hope someone would able to assist me on this. Thank you in advance.
