# PCP Client Authentication Configuration File
# ============================================
#
# This file contains user ID and his password for pgpool
# communication manager authentication.
#
# Note that users defined here do not need to be PostgreSQL
# users. These users are authorized ONLY for pgpool 
# communication manager.
#
# File Format
# ===========
#
# List one UserID and password on a single line. They must
# be concatenated together using ':' (colon) between them.
# No spaces or tabs are allowed anywhere in the line.
#
# Example:
# postgres:e8a48653851e28c69d0506508fb27fc5
#
# Be aware that there will be no spaces or tabs at the
# beginning of the line! although the above example looks
# like so.
#
# Lines beginning with '#' (pound) are comments and will
# be ignored. Again, no spaces or tabs allowed before '#'.

# USERID:MD5PASSWD

# ----------------------------
# pgPool-II configuration file
# ----------------------------
#
# This file consists of lines of the form:
#
#   name = value
#
# Whitespace may be used.  Comments are introduced with "#" anywhere on a line.
# The complete list of parameter names and allowed values can be found in the
# pgPool-II documentation.
#
# This file is read on server startup and when the server receives a SIGHUP
# signal.  If you edit the file on a running system, you have to SIGHUP the
# server for the changes to take effect, or use "pgpool reload".  Some
# parameters, which are marked below, require a server shutdown and restart to
# take effect.

# pgpool Client Authentication Configuration File
# ===============================================
#
# The format rule in this file follows the rules in the PostgreSQL
# Administrator's Guide. Refer to chapter "Client Authentication" for a
# complete description.  A short synopsis follows.
#
# This file controls: which hosts are allowed to connect, how clients
# are authenticated, which user names they can use, which databases they
# can access.  Records take one of these forms:
#
# local      DATABASE  USER  METHOD  [OPTION]
# host       DATABASE  USER  ADDRESS  METHOD  [OPTIONS]
# hostssl    DATABASE  USER  ADDRESS  METHOD  [OPTIONS]
# hostnossl  DATABASE  USER  ADDRESS  METHOD  [OPTIONS]
#
# (The uppercase items must be replaced by actual values.)
#
# The first field is the connection type: "local" is a Unix-domain
# socket, "host" is either a plain or SSL-encrypted TCP/IP socket.
# "hostssl" is an SSL-encrypted TCP/IP socket, and "hostnossl" is a
# plain TCP/IP socket.
#
# DATABASE can be "all", "sameuser", a database name, or a comma-separated
# list thereof. Note that "samegroup" like in PostgreSQL's pg_hba.conf
# file is not supported, since pgpool does not know which group a user
# belongs to. Also note that the database specified here may not exist in
# the backend PostgreSQL. pgpool will authenticate based on the database's
# name, not based on whether it exists or not.
#
# USER can be "all", a user name, or a comma-separated list thereof.  In
# both the DATABASE and USER fields you can also write a file name prefixed
# with "@" to include names from a separate file. Note that a group name
# prefixed with "+" like in PostgreSQL's pg_hba.conf file is not supported
# because of the same reason as "samegroup" token. Also note that a user
# name specified here may not exist in the backend PostgreSQL. pgpool will
# authenticate based on the user's name, not based on whether he/she exists.
#
# CIDR-ADDRESS specifies the set of hosts the record matches.
# It is made up of an IP address and a CIDR mask that is an integer
# (between 0 and 32 (IPv4) that specifies the number of significant bits in
# the mask.  Alternatively, you can write an IP address and netmask in
# separate columns to specify the set of hosts.
#
# METHOD can be "trust", "reject", "md5" , "scram-sha-256" or "pam".
# Note that "pam" sends passwords in clear text.
#
# OPTION is the name of the PAM service. Default service name is "pgpool"
#
# Database and user names containing spaces, commas, quotes and other special
# characters must be quoted. Quoting one of the keywords "all" or "sameuser"
# makes the name lose its special character, and just match a database or
# username with that name.
#
# This file is read on pgpool startup.  If you edit the file on a running
# system, you have to restart the pgpool  for the changes to take effect.

# Put your actual configuration here
# ----------------------------------
#
# If you want to allow non-local connections, you need to add more
# "host" records. In that case you will also need to make pgpool listen
# on a non-local interface via the listen_addresses configuration parameter.
#

# TYPE  DATABASE    USER        CIDR-ADDRESS          METHOD

# "local" is for Unix domain socket connections only
local   all         all                               trust
# IPv4 local connections:
host    all         all         127.0.0.1/32          trust
host    all         all         ::1/128               trust

host    all         pgpool         0.0.0.0/32            trust
host    all         postgres       0.0.0.0/32            trust

It seems that you are missing some watchdog configurations.

For example:

  wd_hostname = ''

Here is an configuration example:
https://www.pgpool.net/docs/41/en/html/example-cluster.html#EXAMPLE-CLUSTER-PGPOOL-CONFIG-WATCHDOG

And another error is:
------
LOG: failed to connect to PostgreSQL server on "192.168.163.129:5432", getsockopt() detected error "Connection ref
used"
2021-07-28 10:32:57: pid 29810: ERROR: failed to make persistent db connection
2021-07-28 10:32:57: pid 29810: DETAIL: connection to host:"192.168.163.129:5432" failed
------

It seems Pgpool-II can't connect to PostgreSQL on 192.168.163.129.
Is PostgreSQL on 192.168.163.129 running?
