Not able to connect to slave machine in case of master is down in redis sentinel configuration, all are running in Docker container

I have 1 master(6379), 1 slave(6380), and 3 sentinels(26379, 26380, 26381) running on docker container master and slave are connected and up even sentinels are giving right information about master-slave.

When I do my query with master and slave both up, it is running fine and I could see(through exposed ports) the same data in both(sync between master and slave is fine).

When I pause master, sentinels act and make slave new master but this time when I try to access redis through my code it is not able to connect and Redis command timed out nested exception is io.lettuce.core.RedisCommandTimeoutException is thrown.
