AWS RedisCache Failover requests

[musicallyvk]

Hi Everyone, Hope everyone is doing great!
so i have a 3 replica and 1 primary on aws elasticache redisCache using version 4.0, with the redis config file on the application level which has a load balancer with round robbin and using replicatedServersConfig. and many other things like retry , failedSlaveCheckInterval,timeout, readMode , subscriptionMode and many things.

if you need more details on config then -

des.redisson.config={"replicatedServersConfig":{"idleConnectionTimeout":10000,"connectTimeout":10000,"timeout":30000,"retryAttempts":3,"retryInterval":1500,"failedSlaveReconnectionInterval":3000,"failedSlaveCheckInterval":60000,"password":"*****","subscriptionsPerConnection":5,"clientName":"myClientName","loadBalancer":{"class":"org.redisson.connection.balancer.RoundRobinLoadBalancer"},"subscriptionConnectionMinimumIdleSize":1,"subscriptionConnectionPoolSize":50,"slaveConnectionMinimumIdleSize":24,"slaveConnectionPoolSize":64,"masterConnectionMinimumIdleSize":24,"masterConnectionPoolSize":64,"readMode":"SLAVE","subscriptionMode":"SLAVE","nodeAddresses":["rediss://Node1,Node2,Node3,Node4"],"scanInterval":1000},"threads":16,"nettyThreads":32,"codec":{"class":"org.redisson.codec.LZ4Codec"},"transportMode":"NIO"}

now the thing is if a failover happens then some requests are still being routed to that failed node, how to get it resolved, anyone please help me. i am stuck with this for months.
Thanks Already !
