There is nothing wrong on your Gateway; it just forwards EAP
authentication between clients and your AAA. You should take a look at
your client and the terminating RADIUS server log.

The problem probably is that your AAA is proposing PEAP. On NM, you can
configure a single server certificate only. Is the AAA PEAP certificate
the same that you use to authenticate the gateway? Does your AAA expect
a client certificate to do mutual PEAP authentication before running the
inner EAP method?
