This is wrong:

```auto
discovery.zen.ping.unicast.hosts: ["192.168.x.xxx:9200", "192.168.y.yyy:9200"]

```

This should be:

```auto
discovery.zen.ping.unicast.hosts: ["192.168.x.xxx:9300", "192.168.y.yyy:9300"]

```

Or easier:

```auto
discovery.zen.ping.unicast.hosts: ["192.168.x.xxx", "192.168.y.yyy"]

```

Every node has to be in a different file, right?

Can you share the logs of both nodes, please?  
Please format them using the `</>` icon to have something like:

```auto
THIS IS A LOG LINE
ANOTHER LOG LINE

```

Thanks.

From the error, my best guess is that one of these IP addresses is incorrect. But it's impossible for us to give you much advice since you're redacting them.  
Are the IP addresses on your private network really so sensitive that you need to make debugging 10 times harder by hiding them?
