Answer 1

Hello,

This error message, Reason Code 22, indicates that the client could not be authenticated because the Extensible Authentication Protocol (EAP) Type cannot be processed by the server. This typically happens when the Network Policy Server (NPS) is unable to handle the specific EAP type being used by the client.

Here are a few steps you can take to troubleshoot this issue:

Verify EAP Configuration: Ensure that the EAP type configured on the client matches the EAP type supported by the NPS server.

Check Certificates: If you’re using certificate-based authentication (like EAP-TLS), make sure that the certificates on both the client and server are valid and properly configured.

Update NPS Policies: Review and update the NPS policies to ensure they are correctly set up to handle the EAP type in question.

Review Logs: Check the NPS logs for more detailed error messages that might give additional clues about the issue.

Best Regards,
