I also had to edit the TNSNAMES.ORA on the STBY server for the correct *VIP* entry (not the physical hostname) for the RAC1 instance.

RAC1 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.78.61)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = RAC.racattack)
    )
  )

RAC1_DGB =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.78.61)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = RAC_DGMGRL)
    )
  )


Thereafter, it worked.  Note : You sometimes have to wait a while to enter the SHOW CONFIGURATION, the first result may show an error.  So I entered it twice.

DGMGRL> disable configuration;
Disabled.
DGMGRL> enable configuration;
Enabled.
DGMGRL> show configuration;

These are the drcSTBY.log entries when the TNSNAMES.ORA for RAC1 was incorrect on the Standby Server :

Failed to connect to remote database rac. Error is ORA-12541
Failed to send message to site rac. Error code is ORA-12541.


This is the drcSTBY.log entry on success :

03/27/2017 23:00:51
Apply Instance for Database stby set to STBY


And the entry in drcRAC1.log on success :

03/27/2017 23:00:10
DISABLE CONFIGURATION
03/27/2017 23:00:46
ENABLE CONFIGURATION
03/27/2017 23:00:57
EDIT DATABASE stby SET PROPERTY ActualApplyInstance = STBY
03/27/2017 23:01:00
