I have two machines using elasticSearch, each machine I have the following configuration set **Machine 1** ```auto cluster.name: NDC node.name: node-1 node.roles: [master, data] network.host: 30.30.30.65 http.port: 9200 discovery.seed_hosts: ["30.30.30.65:9200", "30.30.30.15:9200"] cluster.initial_master_nodes: node-1, node-2 ``` **Machine 2** ```auto cluster.name: NDC node.name: node-2 node.roles: [master, data] network.host: 30.30.30.15 http.port: 9200 discovery.seed_hosts: ["30.30.30.65", "30.30.30.15"] cluster.initial_master_nodes: node-1, node-2 ``` I want to be able to transport data through each other but I can't. Can anyone help me? ---

> [@quanganhhnv](#): > > `discovery.seed_hosts: ["30.30.30.65:9200", "30.30.30.15:9200"]` Elasticsearch nodes communicate over port `9300`, not `9200`, so you have the wrong port specified here. As `9300` is default you can remove port completely here. Also make sure port 9300 is not blocked by firewall. ---

Yes, thank for reply, i was removed port. After that, I could ping each other to port 9300 and 9200, but still couldn't see the index and synchronize each other's data. Am I missing anything? ![image](https://us1.discourse-cdn.com/elastic/original/3X/6/c/6c0ca079b0fae48b24cf29a788c3226841907cfa.png) ---

I do not see anything obviously wrong. Are both nodes able to connect to the other on port 9300? What is in the Elasticsearch logs on the two nodes? ---

Yes, sir. Both nodes able to connect to the other on port 9300. This my Elasticsearch logs. It's nothing here because i was started success today ![image](https://us1.discourse-cdn.com/elastic/original/3X/2/f/2f32ffee23516464e97bd6edaa62aff27eeb4b03.png) ![image](https://us1.discourse-cdn.com/elastic/original/3X/d/3/d3a6c00df3d61e310c8ec550dd0dabe4b1100d9e.png) ---

It looks like node 2 has previously started up as a standalone cluster and therefore can not join the other node. I would recommend shutting down node 2 and clear its data directory so it can join as a new, empty node. It is worth noting that [having 2 nodes being master eligible is bad practice as it does not give you any resilience or high availability](https://www.elastic.co/guide/en/elasticsearch/reference/8.12/high-availability-cluster-design.html). If any one of the nodes go down your cluster will be inoperable. I would therefore recommend adding one more master eligible node to the cluster. This can be a smaller didicated master node and does not necessarily need to be the same size and specification as the 2 master/data nodes. ---

So I will only set 1 node as master, right? ---

> [@quanganhhnv](#): > > So I will only set 1 node as master, right? If you only have 1 master eligible node you can handle the dedicated data node going down, but if the master node fails the cluster will still be inoperable and if it can not be restored you may lose the data unless you can restore from a snapshot. It is better to set up a 3-node cluster where all nodes are master eligible. ---
