Appears to be a firewall issue. I made a dummy PHP script that opens
connection and does simple post without curl. So, it hangs like the curl
test. But for some reason only on multipart/form-data posts. Disabling
firewall allows multipart post.. so I think there's not a curl issue here.

<?php
$postdata=file_get_contents('0000000110');
$opts = array(
        'http' => array(
                'method' => 'POST',
                'header' => [
                        'Content-Type: multipart/form-data;
boundary=---------------------------84927149120355803091994092429',
                        'Content-Length: '.strlen($postdata)
                ],
                'content' => $postdata
                ),
                'ssl' => array(
                'verify_peer' => false,
                'ciphers' => 'HIGH:!SSLv2:!SSLv3'
                )
        );
$ctx = stream_context_create($opts);
$form = file_get_contents('https://hub.zilla.tech/filepost.php', false,
$ctx);
echo $form;
