Why this happens? Because the ANONYMOUS account is locked and/or expired.

Log in to main container database (not PDB)

Run the following query to determine status:

select account_status from dba_users where username = 'ANONYMOUS';

If account_status is expired, run the following:

alter user ANONYMOUS identified by anonymous;

alter user ANONYMOUS account unlock;

If account_status is locked, run the following:

alter user ANONYMOUS account unlock;
