[20:57:05 ERROR] [votingplugin]: Mysql is not loaded correctly, stopping vote processing

I followed https://wiki.bencodez.com/en/VotingPlugin/proxy-method-MYSQL

Not sure where the error came from; mysql hosting, server hosting, the plugin themself, or vote sites (unlikely)

Used diffchecker to check whether there are any credential errors in all of the configs, nothing different after checking

Kinda stuck, any help would be appreciated

Try this https://wiki.bencodez.com/VotingPlugin/Proxy-method-PLUGINMESSAGING and send your startup log

It works, thanks!

Kinda embarassing that... mysql driver.jar isn't loaded correctly during startup
Now mysql error no longer appears, but I haven't tested the voting on each backend servers yet, I might open new issue if something goes wrong, but hopefully not 😅
