Operation timeout exception when querying a node in LAN

var queryRequest = new QueryRequest().Statement("CREATE PRIMARY INDEX ON default using view");
IQueryResult<dynamic> result = cli.Query<dynamic>(queryRequest);

throw operation time out at

System.Net.HttpWebRequest.GetRequestStream(TransportContext& context)
at System.Net.HttpWebRequest.GetRequestStream()
at Couchbase.N1QL.QueryClient.Post[T](IQueryRequest queryRequest) in c:\sources\couchbase-net-client\Src\Couchbase\N1QL\QueryClient.cs:line 197

This was timing out because the sdk was connecting to the data node.
