我尝试使用我的 Minecraft 服务器 (Java) 访问我的 MySQL 数据库 - 论文 1.16.5。但是有这个问题:

The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

我在 KVM 根服务器上使用 Debian 10。这是 my.cnf 文件：

[client-server]
socket = /run/mysqld/mysqld.sock
bind-address    = 0.0.0.0
!includedir /etc/mysql/conf.d/
!includedir /etc/mysql/mariadb.conf.d/

这是mysql.cnf:

[mysql]
bind-address = 0.0.0.0

有什么问题？
