Unable to connect to server with changed view/capi port



I’m running Couchbase server community 4.0 couchbase-client 2.3.2.

I’ve changed all couchbase ports from the default ports (both in static_config and capi.ini).

this is my code:

    final CouchbaseEnvironment env = DefaultCouchbaseEnvironment.builder()
    return CouchbaseCluster.create(env, "");

However I get this error message:

2016-09-30 15:43:48.441 [] WARN c.c.c.c.e.Endpoint - [null][ViewEndpoint]: Could not connect to endpoint, retrying with delay 4096 MILLISECONDS: ! java.net.ConnectException: Connection refused: /

I can access in my browser (9092 is the port I changed it to in couchbase)
But I can’t really figure out how to get the client to connect using that port. I solved port 8093 by adding {query_port, 9093}.to static_config (a option that is not documented on Network Configuration )


Hi @richard.tjerngren,

The client gets the port information from the server. Do you see a json response with couchdb property when you access the port from a browser/curl?


If I access couchbase on the capi port with a browser (which I changed from 8092 to 9092) I get the following response:



Just verifying something is listening on that port doesn’t mean it’s necessarily been changed correctly. Note that static_config and the ini file are read and put into a cluster configuration at configuration time only. If you change them after this, the changes may not take effect.

One quick way to verify this is to visit /pools/default/buckets/<bucket name> with your browser or your favorite HTTP rest test tool. Another more complete way is probably to just turn the log level up to finest and try to do a single operation. You should see the configuration the client is receiving from your cluster there in the log.


Thanks for your response, I’ve attached the output of that querying that url below,
I see no mention of of the port I tried to change, should it be there?

I dug this out of the logs on the client:

2016-10-06 13:22:40.823 [] DEBUG c.c.c.c.c.ConfigurationProvider - Applying new configuration
nodeInfo=[NodeInfo{, hostname=/, configPort=0, directServices={QUERY=9093, BINARY=22000, VIEW=8092, CONFIG=9091}, sslServices={}}]

So it really seems like couchbase doesn’t send the changed view port information to the client, I’m suspecting it is because I’ve only changed it in capi.ini and not static_config (the documentation doesn’t say you need to change it in static_config though)


I finally got it to work, so for people who get here and are stuck: I added “{capi_port, 9092}.” to the file (which is completely undocumented…) and now it works
