The "streaming_barman" user should be a user with replication permissions
(if not already set, execute "ALTER USER streaming_barman REPLICATION")
and appropriate permission granted in "pg_hba.conf":

   host replication streaming_barman  <my-barman-ipaddress-here>/32    md5

Check the replication connection works with:

   psql -c 'IDENTIFY_SYSTEM' 'host=<my-ipaddress-here> dbname=postgres user=streaming_barman replication=1'
