I have two Apache tomcat 8.5.29 pods with proper communication between them and i have been trying to setup cluster with this two pods using multicast IP address 228.0.0.4 and the port 45564.But the cluster is not working as i am getting the below log in the catalina.out while starting the tomcat.
skipping state transfer. No members active in cluster group.
Below is my server.xml
