Unable to switch from replica ( promoted as master when master had failed) to replica-2 when replica is failed

[GajaHebbar]

using primary-replica create pr-primary, pr-replica and pr-replica-2 pods
run watch to monitor and switch master in case of failure.

Kill the pr-primary. watcher identifies the master failure and promotes pr-replica as master.

After this we can insert/delete database entries ( working file as expected)

now kill the pr-replica ( labelled as pr-primary after original pr-primary is killed)
watcher does not initiate failover
watcher logs for 1st failover(successful) and 2nd failover (does not failover)
