What could be causing the error message "php_network_getaddresses: getaddrinfo failed: Name or service not known" during the order process?

The error message "php_network_getaddresses: getaddrinfo failed: Name or service not known" is likely caused by a DNS resolution issue. This means that the server is unable to resolve the hostname of the service it is trying to connect to. To solve this issue, you can try using the IP address directly instead of the hostname in the connection string.

// Before
$hostname = 'example.com';
$connection = mysqli_connect($hostname, $username, $password, $database);

// After
$ip_address = gethostbyname('example.com');
$connection = mysqli_connect($ip_address, $username, $password, $database);
