springboot Lettuce adaptive refresh not working

I am using spring latest version 2.3.1 and lettuce adaptive refresh is not working for me.

I am using 1 Master 2 Slave and 2 sentinel node, i have deployed the application in docker containers, in AWS ec2 ubuntu instance.

When master node dies then i am getting connection time out

io.lettuce.core.RedisCommandTimeoutException: Command timed out after 1 minute(s)

here is the application.yaml file configuration for redis

cache:
    type: redis  
    redis:
      cache-null-values: false
      time-to-live: 100000
      use-key-prefix: true

  redis:
    sentinel:
      master: mymaster
      nodes:
        - redis-sentinel:26379
        - redis-sentinel-1:26380
    timeout: 10s


    lettuce:
      pool:
        max-idle: -1
        max-active: -1
        max-wait: 2s
      cluster:
        refresh:
          adaptive: true
          period: 5s

Thanks for the report, but I think this is likely to be an issue with the Lettuce driver rather than something in Spring Boot's control. Please raise an issue with the Lettuce team here.
