Description:
Hello,
I have Barman installed on a seperate VM and I am trying to configure the
Postgres Server, which is behind a TLS SNI Aware Proxy.
Normal PSQL Connections are working, but I get an error message when I
configure barman with the following streaming_conn_info:
streaming_conninfo = host=pgctest01-rw.dbms.development.cloud.internal
user=postgres dbname=postgres sslmode=require sslnegotiation=direct
pg_hba:
- hostssl all all 0.0.0.0/0 scram-sha-256
- hostssl replication postgres 0.0.0.0/0 scram-sha-256
Error Message:
2026-06-08 13:51:48,496 [318870] barman.postgres WARNING: Error retrieving
PostgreSQL status: connection to server at
"pgctest01-rw.dbms.development.cloud.internal" (10.101.14.225), port 5432
failed: FATAL: no pg_hba.conf entry for replication connection from host
"240.13.11.16", user "postgres", no encryption
When I adjust the pg_hba to following configuration I dont get any error
messages anymore and the connection seems to be encrypted when inspecting
the interface via tcpdump.
Can someone explain me why I am getting this error message even when I force
sslmode and sslnegotiation ?
pg_hba:
- hostssl all all 0.0.0.0/0 scram-sha-256
- host replication postgres 0.0.0.0/0 scram-sha-256
Best Regards
Marijo
