Hi,
I have an Elasticsearch cluster running in the cloud and I am trying to
connect from a java client locally. Due to firewall restrictions I am not
allowed to connect out on port 9300 from my local client. I have created a
proxy in the cloud to forward all TCP connections from port 80 to port 9300
on the cluster master node. My client has the same cluster name as the
master.
In my Java code I have
Settings settings = ImmutableSettings.settingsBuilder().put("cluster.name",
"mycluster").build();
TransportClient client = new TransportClient(settings);
client.addTransportAddress(new
InetSocketTransportAddress("{my-proxy-host-ip}", 80));
When trying to access the client I get
[10:00:44] netty - [Hellion] exception caught on transport layer [[id:
0x2882f1d8, /145.36.217.4:49318 => /{my-proxy-host-ip}:80]], closing
connection

(I have confirmed the route to the master node via the proxy by changing
the outbound port on the proxy server to 9200 and successfully testing curl
{my-proxy-host-ip} OK)
I can't see any reason why this shouldn't work so any ideas are welcomed.
Thanks in advance.
Kim
