Redis could not be reconnected on Linux, but could work on Mac.

Version: 2.7.1
Code:

       redis.createClient(redisUrl, {
        connect_timeout: 60 * 1000,
        retry_strategy: function (options) {
          if (options.error && options.error.code === 'ECONNREFUSED') {
            return new Error('The server refused the connection');
          }
          if (options.total_retry_time > 1000 * 60) {
            return new Error('Retry time exhausted');
          }
          if (options.attempt > 10) {
            return undefined;
          }
          return 60000;
        }
      })

I just expect that the node redis could detect the disconnection in 1 mins and reconnect to redis server in given time successfully when the redis server is ready, but this code dose not work on my Linux env (Ubuntu 18.04), it could work on my Mac env, so could any experts give some help?

Start with the redis.createClient call and its retry_strategy on Ubuntu 18.04, then reproduce the Redis disconnection and compare the Linux behavior with the reported Mac behavior. Trace whether the client detects the failure and retries as configured; done means reconnecting successfully when the Redis server becomes available again.
