can not connect to DR server using sys and system user while creating oracle dataguard in 12c ORA-03

Hi,

I am not able to connect to sys and system user from DR side to primary database while creating oracle dataguard in Oracle 12c.I have copied password file multiple times.For this reason RFS process is not able to start.I am able to connect to the container database from a normal user from DR.
