Hi, Unfortunately, the MySQL driver pre-installed in version 4.0 of CloverETL is not compatible with MySQL 8.0. If you are not able to upgrade to our newest version of Designer, you will have to download the newest MySQL driver and add it manually in the CloverETL Designer. If you look at the screenshot you provided you will notice a plus sign where all available drivers are available, that should allow you to add custom drivers to the already existing ones. Please let me know if you run into any issues. Thanks,
