ORA-16664 error when using ASM filesystem

We have received ORA-16664: unable to receive the result from a database error when enabling the DataGuard broker config

DGMGRL> show configuration verbose;

Configuration - ORCL_DG

Protection Mode: MaxAvailability
orcl - Primary database
orlc_stdby - Physical standby database
Error: ORA-16664: unable to receive the result from a database

1. In one of the senario the problem was in the Primary's REDO_TRANSPORT_USER init parameter
The value for this parameter had weird characters and removing helped.

SQL> show parameter redo_transport

NAME TYPE                               VALUE
------------------------------------ --------------------------------
redo_transport_user string          ???DG_USER???

2. The database is running on ASM and running on ASM and Data Guard Broker configuration files were created locally on filesystem.

In this case drop the existing broker configuration from primary and standby local filesystem and creating on broker configuration on ASM helped.
