我将服务器更新为Debian Buster，现在Prosody 0.11.2-1拒绝连接到MySQL数据库。看来Prosody可以正常启动，但是没有用户能够登录其帐户。如果我查看调试日志，则会看到以下内容：
Nov 30 22:09:15 sql debug Connecting to [MySQL] prosody...
Nov 30 22:09:15 sql debug Database connection was closed. Will reconnect and retry.

Lua版本为5.2.4，同时安装了“ lua-dbi-mysql / stable，现在为0.7.1-2 amd64”和“ lua-sql-mysql / stable，现在为2.3.4-1 + b1 amd64”
