Java.lang.RuntimeException: java.net.ConnectException

Hey, I’m trying to run this simple code… for some reason it takes a lot of time to open the bucket and then i immediately get this exception:
Any ideas what could be the problem?

CODE:
Cluster cluster = CouchbaseCluster.create(DefaultCouchbaseEnvironment.builder().
connectTimeout(100000000).managementTimeout(100000000).queryTimeout(1000000000)
.socketConnectTimeout(1000000000)// 10000ms = 10s, default is 5s
.queryEnabled(true).build(),new String[]{“xx.xxx.xxx.xxx”,“yy.yyy.yyy.yyy”});
System.out.println(“1”);
Bucket bucket = cluster.openBucket(“stats”);
System.out.println(“XXX”);
System.out.println(bucket.bucketManager().getDesignDocuments().size());

EXCEPTION:

It looks like you provide two IPs in the cluster, which contains at least a third node, the Z one. Is the Z ip reachable from your client machine? on any couchbase port (essentially 11210, 8091, 8092, 8093…)?

Sorry for the late reply, i wasn’t around lately
The cluster contian 6 nodes. The Z ip is reachable from my client machine on 8091. @simonbasle

the stack trace indicates that the network component couldn’t establish a connection to that IP on port 8091, so I think there is something going on at the network level…
