nc command kept the connection open upon successful connection to port 6379, thus unable to register to result. My workaround is to add '-q 2' parameters to nc, in so that nc will close the connection in 2 seconds. Like this :

action: shell (echo PING; sleep 1) | nc -q 2 {{ ansible_host }} {{ redis.port }}
