If your website is hosted in Hostinger and you are receiving an error with max_connections_per_hour limit:
Connection failed: User 'u1000000_database' has exceeded the 'max_connections_per_hour' resource (current value: 500)
Try these things:
Option 1 - Use Localhost
Make sure that in your database configuration file, such as wp-config.php the database hostname is set to the localhost.
We don't recommend setting your database hostname to server IP.
Example (incorrect):
/** The name of the database for WordPress */
define( 'DB_NAME', 'u1000000_database' );
/** MySQL hostname */
define( 'DB_HOST', '104.20.160.69' );
Example (correct):
/** The name of the database for WordPress */
define( 'DB_NAME', 'u1000000_database' );
/** MySQL hostname */
define( 'DB_HOST', 'localhost' );
Option 2 - Stop the processes
Some unoptimized code on your website can cause you to reach max_user_connections limits. To solve this you can terminate such connections manually as guided here:
Open your database via phpMyAdmin
Click SQL on the top menu, type SHOW PROCESSLIST and click GO:
Once that's done you will see the list of current processes, you can stop it by clicking on Stop the process:
It's worth noting that this option only helps temporarily, to solve such issues for good, you would need to optimize your database queries or upgrade your plan.
