unable to use remote MySQL database when i set it to use remote mysql database and restart the software it reverts back to using the derby database

I’m having issues with using a remote SQL database aswell. It was working fine, but suddenly stopped

The version is JBidwatcher 2.99pre5-2-g7251940

Even when I specify the database details in the cfg file it says along the lines of cannot connect to database ’ ’

Any help would be appreciated
