I'm assuming this is an issue with the MySQL server but am posting a report anyways.

False information.

This exception is the result of not having your username/password/host right. PreciousStones will throw this error and then continue with loading, but then find no results to work with.

Control your settings. If you use an external mysql server make sure it accepts the connection.

Edit: corrected.
