I have connected LuckPerms to a MySql, and at first it connected fine, but when I reboot in the vps, it gives me an error.
MySql is started, i can login and manage it.

Hello, your MySQL server is active?

Hello, your MySQL server is active?

Yes

You didn't defined password in config:

password: 'passwordhere'

Or maybe you done that for hide it. Maybe you MySQL port is not open.

"Connection refused" error

Could be wrong password, bad firewall config, bad MySQL server config....

but nothing to do with LuckPerms. :)
