" no cipher suites in common" seen in WebSphere Application Server Node Agent logs

Following hot on the heels from my last post: -

I started seeing: -

[26/03/16 15:38:45:206 GMT] 00000048 SSLHandshakeE E   SSLC0008E: Unable to initialize SSL connection.  Unauthorized access was denied or security settings have expired.  Exception is no cipher suites in common
Caused by: no cipher suites in common
[26/03/16 15:41:13:771 GMT] 00000075 ORBRas        E createSSLSocket ProcessDiscovery : 0 JSSL0080E: - The client and server could not negotiate the desired level of security.  Reason: Received fatal alert: handshake_failure Received fatal alert: handshake_failure

in the SystemOut.log of the Node Agent.

The solution was, thankfully, the same; I updated the node-level ssl.client.props : -

vi /opt/IBM/WebSphere/AppServer/profiles/AppSrv01/properties/ssl.client.props 

and adding: - TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
