Couchbase ExectureStore失敗「無法找到節點」

當我嘗試做以下：Couchbase ExectureStore失敗「無法找到節點」

using (var couch = new CouchbaseClient()) { 
    couch.ExecuteStore(StoreMode.Add, idList[0].Id, seralisedList[0], PersistTo.One); 
}

我得到

System.NullReferenceException was unhandled 
    HResult=-2147467261 
    Message=Object reference not set to an instance of an object. 
    Source=Couchbase

而且在檢查的CouchBaseClient.ExecuteGet("name1")的返回值，我注意到"Unable to locate node"作爲Message的GetOperationResult

在訪問http://192.168.0.48:8091/pools/default/bucketsStreaming/default?bucket_uuid=d8bd12df7bd818663d0fd85a200edabf沒有任何反應，直到超時。所以這似乎是根本原因。

你有所有需要打開的端口？ http://docs.couchbase.com/couchbase-manual-2.2/#network-ports 您可能需要通過ufw打開ubuntu實例上的端口 https://help.ubuntu.com/community/UFW – scalabilitysolved

所以「修復」就是摧毀虛擬機並重新構建它。只是卸載couchbase服務器似乎沒有辦法。

這似乎是問題是由於DHCP /沒有一個靜態IP。希望現在我已經爲虛擬機預留了DHCP租約，不會再有任何問題。（它今天早上打破了IP地址更改。）
