Thanks for the response! I did follow this example
https://people.apache.org/~markt/dev/server-static-cluster-example.xml. The
only difference being that I am using tomcat 8.5 so I am using the
StaticMembershipInterceptor instead. In my second email, I have followed
this configuration, however I encounter the error -
*12-Jun-2023 14:18:26.507 SEVERE [Tribes-Task-Receiver[Catalina-Channel]-3]
org.apache.catalina.tribes.io.XByteBuffer.append Discarded the package,
invalid header*
I am copying that email here for your reference. *Cluster settings - *

*Logs,*
I get the following error log on the node with port 8090 when I try to
access it from the browser (through an nginx load balancer that I have
configured and even when accessed directly).
