postgresql - [Postgres Replication]Remote host is not reachable repmgr salve -

i trying create postgres replication configuration using 2 servers. steps similar postgresql 9.4 replication repmgr , pgbouncer on ubuntu 14.04 . using repmgr + pgbouncer replication configuration. have 2 host dhost1 , dhost2. repmgr meta data db repmgrdb , user repmgr_user.
dhost1 has pgbouncer , repmgr's configuration , master. repmgr's configuration in dbhost1 mentioned below:

>cluster = test  >node = 1   >node_name = dhost1   >use_replication_slots = 1   >conninfo='host=dhost1 user=repmgr_user dbname=repmgrdb'   >pg_bindir=/usr/lib/postgresql/9.5/bin > ## repmgr.conf @ master ## 

dhost2 has repmgr's config , in slave mode. it's config mentioned below

>cluster = test  >node = 2   >node_name = dhost2   >use_replication_slots = 1   >conninfo='host=dhost2 user=repmgr_user dbname=repmgrdb'   >pg_bindir=/usr/lib/postgresql/9.5/bin > ## repmgr.conf @ slave ## 

i able register master , can seen master in cluster show command.
on slave side using pg_basebackup method clone master command

repmgr -f /etc/repmgr/repmgr.conf --force -h -u repmgr_user -d repmgrdb -v standby clone

for above command below error:

i have set password-less ssh postgres user between dhost1 , dhost2.

also have been able take pg_basebackup command

pg_basebackup -h -p -v -u repmgr_user -x stream -d 9.5/main -r

i beginner postgresql replication please suggest me answers.
