Vladimir, I'm suggesting to share the log files from the nodes that are unable to interconnect so that the community can check them for potential issues. Instead of sharing the logs from all the 5 nodes, try to start a two-nodes cluster with the nodes that fail to discover each other and attach the logs from those.
