StackExchange.Redis集群

Question

StackExchange.Redis连接redis集群
报错：其他信息: Endpoint 127.0.0.1:7002 serving hashslot 15224 is not reachable at this point of time. Please check connectTimeout value. If it is low, try increasing it to give the ConnectionMultiplexer a chance to recover from the network di
sconnect.

代码：
public static ConnectionMultiplexer Instance
{
get
{
if (_instance == null)
{
lock (Locker)
{
if (_instance == null || !_instance.IsConnected)
{
_instance = GetManager();
}
}
}
return _instance;
}
}

    public static ConnectionMultiplexer GetConnectionMultiplexer(string connectionString)
    {
        if (!ConnectionCache.ContainsKey(connectionString))
        {
            ConnectionCache[connectionString] = GetManager(connectionString);
        }
        return ConnectionCache[connectionString];
    }

public bool StringSet(string key, string value, TimeSpan? expiry = default(TimeSpan?))
{
key = AddSysCustomKey(key);

        var profiler = new RedisProfiler();

        _conn.RegisterProfiler(profiler);
        _conn.BeginProfiling(profiler.MyContext);
        var db = _conn.GetDatabase();
        db.StringSet(key, value, expiry);
        db.StringSet("hello", "world");

        var msgs = _conn.FinishProfiling(profiler.MyContext);

        return true;
    }

z这个端口的redis有没有侦听，是不是服务掉线了
