Could not create a connection for cluster node ClusterNode in JBoss EAP 7 / 6

Issue

• We are able to invoke a single node, but when we configure our ejb-client to invoke a cluster, it fails to connect to the cluster nodes with this message:

INFO: Could not create a connection for cluster node ClusterNode{clusterName='ejb', nodeName='node1:server', clientMappings=[ClientMapping{sourceNetworkAddress=/0:0:0:0:0:0:0:0, sourceNetworkMaskBits=0, destinationAddress='192.168.1.100', destinationPort=12345}], resolvedDestination=[Destination address=192.168.1.100, destination port=12345]} in cluster ejb
