AWS EC2 suddenly cannot connect to RDS?

Suddenly, wordpress cannot connect to my RDS. all configurations and inbound/outbound rules are correct. I also tried creating basic php function to connect.. I tried it on my local machine and it's working but not on my EC2 server.

$mysqli_connection = new MySQLi('xxxx.xxxxx.ap-southeast-1.rds.amazonaws.com', 'db_user', 'db_pass', 'db_name');
if ($mysqli_connection->connect_error) {
   echo "Not connected, error: " . $mysqli_connection->connect_error;
}
else {
   echo "Connected.";
}

Error: php_network_getaddresses: getaddrinfo failed: Name or service not known

Just this morning this happened, I didn't do anything at all. Maybe this is an Apache error or something? any help please?

To those who might be facing the same issue. Rebooting the EC2 instance fixed the problem.

Also, check if your volume is not full. run df -a in your ec2 through ssh to check
