Error establishing a database connection

I am using Go Daddy as my host. My wp-config.php reads

<?php
// ** MySQL settings ** //
define('DB_NAME', 'sql_violethour'); // The name of the database
define('DB_USER', 'sql_violethour'); // Your MySQL username
define('DB_PASSWORD', 'mypassword'); // ...and password
define('DB_HOST', 'mysql85.secureserver.net'); // 99% chance you won't need to change this value

// Change the prefix if you want to have multiple blogs in a single database.
$table_prefix = 'wp_'; // example: 'wp_' or 'b2' or 'mylogin_'

// Change this to localize WordPress. A corresponding MO file for the
// chosen language must be installed to wp-includes/languages.
// For example, install de.mo to wp-includes/languages and set WPLANG to 'de'
// to enable German language support.
define ('WPLANG', '');

/* Stop editing */

define('ABSPATH', dirname(__FILE__).'/');
require_once(ABSPATH.'wp-settings.php');
?>

I have a mysql database called sql_violethour created and can create tables in it.
I have disabled my personal firewall and privacy software. I have triple checked username, database name and have tried ‘localhost’ as well as the
‘mysql85.secureserver.net’ value. Anyone have any insights?
