Prosody 在升级到 Debian Buster 后无法连接到 MySQL 数据库

我将我的服务器升级到了 Debian Buster，现在 Prosody 0.11.2-1 无法连接到 MySQL 数据库。它看起来正常启动，但没有用户能够登录他们的帐户。如果我查看调试日志，我会看到这个：

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，并且已安装“lua-dbi-mysql/stable,now 0.7.1-2 amd64”和“lua-sql-mysql/stable,now 2.3.4-1+b1 amd64”。
