One of the following events on primary database may have caused this error:

This error is related with the TNS connect string when connecting to the standby.

This error is related with the Primary Database TNS Alias. Because MSDB is primary and MSDBDG is Standby side.

$ rman target / catalog <username>/<password>@<catalog tns>
RMAN> resync catalog from db_unique_name MSDB;

Use the Standby TNS Alias instead of Primary Alias. To solve this error, use the Standby TNS Alias as follows.

$ rman target <username>/<password>@MSDBDG catalog <username>/<password>@<catalog tns>

RMAN> resync catalog from db_unique_name MSDB;

resyncing from database with DB_UNIQUE_NAME MSDB
