I just installed Mantis using MySQL 8 with an instance that requires encrypted client connections. To get it to work I had to change Line 56 of mantisbt-2.24.0/vendor/adodb/adodb-php/drivers/adodb-mysqli.inc.php to:
var $clientFlags = MYSQLI_CLIENT_SSL;
It would be great if a configuration option to do the same thing could be set in: mantisbt-2.24.0/config/config_inc.php
