Connection Error - DataGrip

Hello,

I'm not able to use DataGrip (Mac) to connect to any of my DBs. I have the latest version of DataGrip installed on a Windows machine and a Macintosh and the Windows version is working fine. I am also able to connect to the databases in question via other tools (Toad, SSH, etc.). I'm including screenshots of a connection I tried to make with a mysql database, but I've tried with Oracle and MSSQL databases and the error persists. Details below:

DataGrip Version: 2017.1.4
macOS Version: 10.12.5

What settings do I need to change to get the product to start working normally?
