ORA-28545 NET8 ERROR Database link oracle to postgresql

So I'm trying to create a database link between oracle and postgresql in the same server, and when I try to do a select it shows me this error. I've been looking for some answers in different forums but my low knowledge about it doesn't let me understand a way to solve the problem. This is the error:

ERROR line 1:
ORA-28545: error diagnosed by Net8 when connecting to an agent
Cannot retrieve text from RED / NCR 65535 message
ORA-02063: 2 lines preceding POSTGRESQLLINK

Here is my tnsnames.ora:

test=(description=
(address_list=
        (address=(protocol=TCP)(host=localhost)(port=5432)))
                (connect_data=(service_name=test)))

POSTGRESQL =
  (DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA =
  (SID = postgresql)
)
(HS = OK)
  )

My listener.ora:

    DEFAULT_SERVICE_LISTENER = XE

    LISTENER =

Sorry if this is an easy problem.
