This question already has an answer here:
Error: Database connection failed
It is possible that the database is overloaded or otherwise not running properly.
The site administrator should also check that the database details have been correctly specified in config.php
Warning: mysqli::mysqli(): (28000/1045): Access denied for user 'moodledude'@'localhost' (using password: YES) in /var/www/html/moodle/lib/dml/mysqli_native_moodle_database.php on line 79
