Not exactly sure what's causing this, if anyone knows please help !
May just be an issue with how I set it up, may be an ignored issue, honestly IDK.

Does that happen after the plugin worked already or does it just not work? If the second one is the case then you probably have an issue in your database setup because this looks like it can't connect to your database server. (Or it's suddenly refusing connections to it)

Ah so I need to set up the db for it....
Any chance of getting help to do so?
Discord or such methods ?

There are tons of guides available online on how to setup a MySQL database. (most linux distributions even come with one pre-installed) Then just enter the values in the config after you setup the database and user.
