Laminas Mail with SMTP not sending mail on development server (but does send on production server)

There is a lot on the web, but i didn’t solve it yet.

I am using laminas mail with an SMTP connection to send mail, this works fine on production server, but for testing purposed i also want to use it on my developmentserver. For some reason it does not work there, with the same settings (see below)

$options   = new SmtpOptions(array(
                'name'              => 'maintenanceplus.nl',
                'host'              => 'mail.antagonist.nl',
                'port'              => 587,
                'connection_class'  => 'login',
                'connection_config' => array(
                    'username' => '****',
                    'password' => '****',
                    'ssl' => 'tls'
                ),
            ));

I am using Apache2 with PHP8.2 on a windows machine.
