I downloaded the redash onto debian, installed it. Then apt-get install mariadb-server… i created the username/password, and checked to make sure mysql client can access. No problem so far.

But when i login to dashboard and try to test connection, I get connection error (screenshot: https://screenshot.net/ee497bp)
Is there more debugging messages I can look at?
