MySQL user accounts are often restricted to connect from specific hosts. If the client is connecting from a host not allowed in the user's grant, you'll get error 2003. Use `SHOW GRANTS FOR ''@'';` to check the user's permissions and update them with `GRANT ALL PRIVILEGES ON *.* TO ''@'' IDENTIFIED BY '';` if necessary (adjust privileges and hostname as needed).
