Are you sure you're binding to the right network interface? What does the startup show as bind_addr in TCP? I suggest explicitly set TCP.bind_addr to 10.1.0.11 or 10.1.0.4 (or use bind_addr="site_local"). Below is the log files for the sample program. Will send across the log for the project as well. ############################################################################################################################################################### azureuser@POCCluster1:~/test/jgroups-3.6.16.Final$ java -Djava.net.preferIPv4Stack=true jGroupTest.ClusterTest Start creating channel Oct 12, 2018 6:13:08 AM org.jgroups.stack.Configurator resolveAndAssignField WARNING: JGRP000014: BasicTCP.use_send_queues has been deprecated: will be removed in 4.0 only connect if we are not a unicast channel : cluster_name : ChatCluster Event Name : connect_event : CONNECT_USE_FLUSH, arg=ChatCluster ------------------------------------------------------------------- GMS: address=POCCluster1-8872, cluster=ChatCluster, physical address= 10.1.0.11:7801 ------------------------------------------------------------------- ** view: [POCCluster1-8872|0] (1) [POCCluster1-8872] Done creating channel > Oct 12, 2018 6:13:14 AM org.jgroups.util.SuppressLog log WARNING: JGRP000012: discarded message from different cluster poc-chat (our cluster is ChatCluster).
