This ORA-28500 errors are related with the Oracle database link created for the foreign datasource has either no credentials or incorrect credentials.

create [public] database link test connect to "user_name" identified by "password" using 'MSDB';

 

Sometimes The issue is caused by a problem with character and language settings.
