[pgpool-general: 6033] failover fails sometimes with failover: set new primary node: -1

[rachel Ajebon]

I am new to pgpool, I have tried setting up  3 pgpool nodes and 3 backend Postgresql databaseand 3 pgppool node  and 2 backend Postgres database.
The issue with the above 2 settings are that I sometimes get this error when performing a failover "failover: set new primary node: -1" and the failover does not occur and all databases becomes standby databases please what does the -1 stand for and what might I be doing wrong. Please let me know.

the second question for the first setup which is 3 pgpool nodes and 3 postgres database, how do I make the second standby sync with the master database after failover? Please let me know.
Thanks so much for your help!
