I'm trying to connect to a MySQL server in order to use global ranks (BungeeCord network). However, I got this error when starting my SkyBlock server:

https://mclo.gs/GSnau3n

At first, I thought it was a connection error, however, it's consistent (it happens every time I restart the server) AND the MySQL connection works fine on both the lobby server and the BungeeCord proxy.

Does anyone know why this is happening?

LuckPerms also constantly spams this line into the console:

https://mclo.gs/GSnau3n#L195

oops

So you seem to have a couple problems here. However, it's this problem that's causing the connection to outright fail.

See line 30 where it reports the following:
[17:10:25 WARN]: Caused by: me.lucko.luckperms.lib.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: User JPIcG8LzOp already has more than 'max_user_connections' active connections

For this issue, read this article on the wiki regarding storage system errors. The fix should be on this page.

For the SSL issue, if you're connecting to a SQL Server running on an internal network (i.e. it's not traversing the internet) or if it lives on the same host as the minecraft server itself (connecting over localhost or 127.0.0.1), you can explicitly disable SSL with useSSL=false in your mysql config and that will get rid of those errors. Otherwise, you can self-sign a certificate and use that for authentication.

If you're self-hosting through a VPS, then Digital Ocean's article on securing a MySQL or MariaDB server may be of use to you. Otherwise, I recommend reaching out to your hosting service and informing them of the SSL errors.
