Cannot connect Barman to PostgreSQL 12 - postgresql

Question

I have 2 ubuntu-20.04 VM on VMWARE with Postgres 12 installed on each
pgprimary on ip 192.168.1.131
pgbackup on ip 192.168.1.130
barman CLI tools are installed on pgprimary
barman is installed on pgbackup
I want to backup data from pgprimary on pgbackupsame 2 users as Postgress users
on each machine I created
2 Linux sudoist users
useradd barman
useradd streaming_barman
also created the same two user as Postgress users
createuser --superuser --replication -P barman
createuser --superuser --replication -P streaming_barman
here are relevant parts on the configuration files
On pgprimary
postgressql.conf
listen_addresses = '*' # what IP address(es) to listen on;
port = 5432
archive_mode = on
archive_command = 'cp %p /var/lib/postgresql/12/arc/%f'
wal_level = replica
restore_command = 'cp /var/lib/postgresql/12/arc/%f %p'
recovery_target_time = '2021-03-24 16:18:11.319298+05:30'
recovery_target_inclusive = false
pg_hba.conf
local all postgres peer
# TYPE DATABASE USER ADDRESS METHOD
local all all peer
host all all 127.0.0.1/32 md5
host all all ::1/128 md5
#local replication all peer
#host replication all 127.0.0.1/32 md5
#host replication all ::1/128 md5
# FOR TESTING
local replication all trust
host replication all 127.0.0.1/32 trust
host replication all ::1/128 trust
also did
firewall-cmd --permanent --add-port=5432/tcp
firewall-cmd --reload
========================
con
On pgbackup
sudo cat <<'EOF' >> /etc/barman.d/pgprimary.conf
[pgprimary]
description = "Example of PostgreSQL Database (Streaming-Only)"
conninfo = host=192.168.1.131 user=barman dbname=training
streaming_conninfo = host=192.168.1.131 user=streaming_barman dbname=training
backup_method = postgres
streaming_archiver = on
slot_name = barman
create_slot = auto
EOF
pg_hba.conf
cat <<'EOF' >>~/.pgpass
pgprimary:*:*:barman:barman
pgprimary:*:*:streaming_barman:barman
EOF
Then I did
barman cron
Output
Starting WAL archiving for server pgprimary
Starting streaming archiver for server pgprimary
barman check pgprimary
Then I get this error
[13643] barman.utils WARNING: Failed opening the requested log file. Using standard error instead.
Server pgprimary:

Why cannot connect barman to the server ?
UPDATE:
psql -h 192.168.1.131 -U barman -d training
Password for user barman:

I also can connect to server via netstat
