Postgresql 9.4 and BDR SELECT bdr.bdr_group_join ERROR

I'm trying to configurate Postgresql 9.4 with BDR, I have two servers where the master has the address 169.254.9.90 and the slave has the address 169.254.12.48. I have already configurated the master but when I try to join the slave to the replication I'm getting an error:

Command to join:

SELECT bdr.bdr_group_join(
    local_node_name := 'node2',
    node_external_dsn := 'host=169.254.12.48 port=5432 user=postgres dbname=amstest password=postgres',
    join_using_dsn := 'host=169.254.9.90 port=5432 user=postgres dbname=amstest password=postgres'
);

The error Im getting is:

ERROR: connection from remote back to local in replication mode failed DETAIL: remote reported: ERROR: establish BDR: FATAL: no pg_hba.conf entry for replication connection from host "169.254.9.90", user "postgres", SSL on FATAL: no pg_hba.conf entry for replication connection from host "169.254.9.90", user "postgres", SSL off

DETAIL: Connection string is 'replication=database fallback_application_name='BDR test connection' connect_timeout=30 keepalives=1 keepalives_idle=20 keepalives_interval=20 keepalives_count=5 host=169.254.12.48 port=5432 user=postgres dbname=amstest password=postgres'

CONTEXT: SQL statement "SELECT *
FROM bdr.bdr_test_remote_connectback(join_using_dsn, node_external_dsn)" PL/pgSQL function bdr_group_join(text,text,text,text,integer,text[]) line 39 at SQL statement

Could anyone help me please?

FATAL: no pg_hba.conf entry for replication connection from host "169.254.9.90", user "postgres"

Each node must be able to connect to each other node, both for replication and non-replication connections.

The newly joining node does not have a pg_hba.conf that permits the existing node you are specifying as a join target to connect to it.
