Been trying to setup the NPS server from my Azure AD to allow my client to join the wifi connection automatically.
After the setup, I tried to connect to that SSID that I've configured but failed.

I saw the log from the "Network Policy and Access Services", I found out the reason code is 9. May I ask is there anybody came across similar issue while you do such setup please?

Authentication Details:
Connection Request Policy Name: Secure Wireless Connections
Network Policy Name: Secure Wireless Coneections
Authentication Provider: Windows
Authentication Server: MY_DC_NAME
Authentication Type: PEAP
EAP Type: Microsoft: Secured password (EAP-MSCHAP v2)
Account Session Identifier: XXXXXX
Reason Code: 9
Reason: The request was discarded by a third-party extension DLL file.

Thanks for helping!

    It's always good to check links with problems similar to ours, because sometimes we find a general solution that helps to solve the problem permanently, so, check the two topics below:

    https://learn.microsoft.com/en-us/answers/questions/399472/azure-ad-joined-devices-nps-eap-types-34secure-pas.html

    I also find it interesting to refer to the article on "Integrate your VPN infrastructure with Azure AD MFA using the Network Policy Server extension for Azure", see the article below:
