You may try to disable session-resumption and see if that fixes the issue. The specific code error:1408E0F4 seems to relate to a cipher mismatch between the client and ClearPass, and I see quite some references to the TLS 1.2 version and it may be that the client is trying to perform TLS1.0 or TLS1.1.
You might check in ClearPass under the Cluster-Wide Parameters, General, if these TLS1.0 and TLS1.1 are disabled for Network or All; and if it is, if you enable it if the issue disappears. Note that if that resolves the issue, you might consider upgrading the client.
If the issue resists, consider opening a support case at Aruba Support TAC through your Aruba partner or direct if you have access.

Hello,
Our client dosen't suport fast roaming, it is possible that the fast roaming and session resumption enabled in authentication methode eap-peap in clearpass cause this problem ?

Hello,
Our client use EAP-GTC without validation of certificate against a local radius database in clearpass.
But often we have this error message while client roam and disconnect the client :
EAP-PEAP: fatal alert by server - unexpected_message
TLS Handshake failed in SSL_read with error:1408E0F4:SSL routines:ssl3_get_message:unexpected message
eap-tls: Error in establishing TLS session
Do you know what does it mean ?
