Scenario:
1. Start Eap (standalone-ha.xml) on Ipv6 address with prefix 2001 (Teredo Tunneling)
2. Look for Mod_cluster Advertising error
Error from ContainerEventHandlerService class

// There should be a socket-binding.... Well no it needs an advertise socket
:-(
final SocketBinding binding = this.binding.getOptionalValue();

config.setAdvertiseSocketAddress(binding.getMulticastSocketAddress());
config.setAdvertiseInterface(binding.getSocketAddress().getAddress());
if
