Simple JSON-RPC call to Bitcoin wallet with Apache Http Client 4 gives "failed to respond"

Question

I'm trying to do simple JSON-RPC call to 'getinfo' method with no parameters with Apache Http-components HttpClient, but all I got is:

org.apache.http.NoHttpResponseException: 127.0.0.1:33002 failed to respond

My JSON RPC request is:

{ "method": "getinfo", "params": [], "id": 1}

And the code is:

CredentialsProvider credsProvider = new BasicCredentialsProvider();
credsProvider.setCredentials(
    new AuthScope( "localhost" , 33002 ) ,
    new UsernamePasswordCredentials( "loginxxx" , "passxxx" ) );

CloseableHttpClient client = HttpClients.custom()
    .setDefaultCredentialsProvider( credsProvider )
    .build();

HttpPost request = new HttpPost( "http://127.0.0.1:33002/jsonrpc" );

request.setEntity( new StringEntity( "{\"method\":\"getinfo\",\"params\":[],\"id\":1}" ) );

HttpResponse response = client.execute( request );

Why server is not responsing? How can I improve my JSON-RPC request?

Edit: changing both hostnames to 127.0.0.1 or both to localhost doesn't helps. Also putting id in \"1\" doesn't helps. EntityUtils.consume also doesn't helps. Removing /jsonrpc from URL also.

The calling code is ok. This issue comes when you configure port setting instead of rpcport in Bitcoin .

So I was connecting to some other service in Bitcoin wallet (propably just a bitcoin network service p2p server).
