Mysql 数据库错误：异常错误：SQLSTATE[HY000][1045]

我在获取错误的服务器上配置网站，CakePHP 3，但当我将浏览器指向某个链接时，会出现以下错误：

config/app.php

If you want to customize this error message, create src/Template/Error/pdo_error.ctp

修复了该问题，使用了以下DB主机名连接：

'Datasources' => [
        'default' => [
            'className' => 'Cake\Database\Connection',
            'driver' => 'Cake\Database\Driver\Mysql',
            'persistent' => false,
            'host' => 'localhost',     
            'username' => 'username',
            'password' => 'password ', 
            'database' => 'DB name',
            'encoding' => 'utf8',
            'timezone' => 'UTC',
            'cacheMetadata' => true,
            'quoteIdentifiers' => false,
            'log' => false,
            //'init' => ['SET GLOBAL innodb_stats_on_metadata = 0'],
            'url' => env('DATABASE_TEST_URL', null),
