Hi,
I'm trying to get or set a string key from redis database after OnConnectionRestored, but the command sometimes failes:

    public void Connect()
    {
      var configuration = new ConfigurationOptions
      {
        AbortOnConnectFail = false,
        ConnectTimeout = 3000,
        SyncTimeout = 5000,
        KeepAlive = 180,
        EndPoints =
        {
          {
            url, Port
          }
        }
      };

      var connectionMultiplexer = ConnectionMultiplexer.Connect(configuration);
      connectionMultiplexer.GetDatabase();

      connectionMultiplexer.ConnectionRestored += OnConnectionRestored;

      var subscriber = connectionMultiplexer.GetSubscriber();
    }    

    private void OnConnectionRestored(object sender, ConnectionFailedEventArgs args)
    {
      var connectionMultiplexer = (ConnectionMultiplexer) sender;
      if (connectionMultiplexer.IsConnected)
      {
        var redisDatabase = connectionMultiplexer.GetDatabase();

        var setStringResult = redisDatabase.StringSet(new[]
        {
          new KeyValuePair<RedisKey, RedisValue>("key", "value")
        });
      }
    }

StackExchange.Redis.RedisConnectionException: 'No connection is active/available to service this operation: SET key, mc: 1/1/0, mgr: 10 of 10 available, clientName: FABIAN-PC, IOCP: (Busy=0,Free=1000,Min=8,Max=1000), WORKER: (Busy=1,Free=32766,Min=8,Max=32767), v: 2.1.30.38891'

FailureType = UnableToResolvePhysicalConnection

Is it possible to observe somehow IDatabase IsConnected? Or is there a problem somewhere else?

Thank you, Tomas
