I'm trying to implement elasticsearch to my remote server where I will deploy my application

when I start my elasticsearch engine with localhost is started correctly but when I change host in elasticsearch.yml to `network.host: 0.0.0.0` the elasticsearch engine is stopping immediatly with the Warning

see

```

```

why I get this warning and why elasticsearch is stopping thanks

If you don't need to have a cluster of multiple nodes, that's probably fine.

You need to set network.host correctly and remove the discovery setting you just added.
