If I use the MariaDB add-on inside of HA, I’m good, but I’m running HA as a VM in Unraid and I would like HA to use the MariaDB instance that’s already running in Docker on my Unraid box.
So, if I reconfigure the connection to point to the server I want, I get an error in HA, and I get an error on the MariaDB database log. Both are below, but I should note that I am able to connect to the database server I want using MySQL Workbench, so I’m not sure what’s causing it…
