I have 3 cluster node out of which one is as a coordinator node with master as false and data as false.
1 and 2 are both master and data node and they work fine in cluster with minimum master node set as 1.
When I am trying to add 3 node in cluster as a coordinator node it is not adding into the cluster and error logs gives failed to communicate to the master node.
I am using 6.8.0 version. Port is default 9200
Network host on all the 3 server is 0.0.0.0
Tried reboot of all the node not helped.
