Elastic TCP node: NoNodeAvailableException

[Lorenzo_Prinsloo]

Some background

Im using TCP client on Scala to connect to my elasticsearch container on docker but im having issues with the client not finding the configured nodes. Im used kitematic to setup the official docker image but have modified the elasticsearch.yml to see if any changes there could fix my problem

val logger = LoggerFactory.getLogger(Logger.ROOT_LOGGER_NAME)
val settings = Settings
.builder()
.put("cluster.name", "elasticsearch")
.put("client.transport.sniff", false)
.build()

lazy val client = TcpClient.transport(settings, ElasticsearchClientUri("localhost", 9300))

client.execute {
 indexInto("bank" / "account") fields
   (
     "account_number" -> 1001,
     "balance" -> 400,
     "firstName" -> "Lorenzo",
    "lastName" -> "Prinsloo",
    "age" -> 23,
    "gender" -> "M",
    "address" -> "4 Durmonte Durbanville",
    "employer" -> "Full Facing",
    "email" -> "cmlprinsloo@gmail.com",
    "city" -> "Cape Town",
    "state" -> "Western Province"
   ) refresh RefreshPolicy.IMMEDIATE
}.await

val resp = client.execute {
 search("bank" / "account") query "Lorenzo"
}.await

println(resp)

client.close()

Using netcat i could query and see my port was indeed open to connections

localhost [127.0.0.1] 9300 (vrace) open

But when i run my service i run into this exception
Exception in thread "main" NoNodeAvailableException[None of the configured nodes are available:
[{#transport#-1}{JJcLvuDWR5aJMHUjl6LsOw}{localhost}{127.0.0.1:9300}]]

my container logs show that the service is booting up properly

Any help would be appreciated
