Are outgoing https calls in OSC disabled - https not in Registered PHP Streams?

Content

If I trigger an outgoing http REST call from OSC, it works.
If I trigger an outgoing https REST call from OSC, it returns an empty  response with no error (see code block)
If I look at the 'registered streams' in phpinfo(), I see that https is not included.

Are outgoing https calls from OSC disabled? Is there a way to enable them?

    array(
        'method'  => 'POST',
        'header'  => "Accept: application/json\r\n" . "Content-Type: application/json\r\n",
