No changes other than maybe an automatic upgrade and recently getting a database error connection. I can reach the database and the credentials are still valid in the wp-config. Where else do the credentials need to go?
class-wpdb.php
mysqli\_real\_connect(): (HY000/2002): Host is unreachable in /config/www/wordpress/wp-includes/class-wpdb.php on line 2019
