我正在尝试使用OPC UA协议读取Hololens2上节点的值

我正在使用OPC UA SDK for.NET（OPC.UaFx.Client 2.14.0）。我使用以下代码连接到服务器：

public bool ConnectToOpcUaMachine(string machineIp) {
    try {
        _client = new OpcClient(machineIp);
        _client.OperationTimeout = 2000;
        _client.Connect();
    } catch( System.Exception ex ) {
        Debug.Log("Couldn't connect to OPC server");
        Debug.LogException(ex);
        return false;
    }
    return true;
}

当我在编辑器中调用此方法时，我成功地连接到服务器，并且可以读取节点值。然而，当我尝试在全息透镜2上做同样的事情时，我得到以下错误：
