NoNodeAvailableException when installing elasticsearch plugin in grails - grails

Question

I'm developing a grails web-app (currently on my local machine) that needs to query elasticsearch on a server on my network.
I have taken the following steps:
Added the following line in BuildConfig.groovy
plugins {
...
runtime ":elasticsearch:0.0.3.4"
...
}
I have also added the following to Config.groovy:
elasticSearch {
client.mode = 'transport'
client.hosts = [
[host:'xxx.xxx.xxx.xxx', port:9200]
]
disableAutoIndex = 'true'
}
To eliminate firewall issues etc have run the query using curl and it works fine:
curl -XGET 'http://xxx.xxx.xxx.xxx:9200/_search?pretty' -d '{...}
But I am getting the following:

I've read numerous other answers on here for similar errors but nothing I've tried is working. Any ideas?

Answer 1

Transport is done on port 9300 (not on the HTTP port 9200). Also check this port to be open then.
If it still fails, check also to use the right cluster.name. It is elasticsearch by default, so if you have not changed it in your server/cluster, there is no need for it.
Otherwise please add the new insights on your question.
