request download recording from moodle plugin

Hi,
This ticket is related with moodle plugin.
We've deployed the last version 3.3.0 lately and integrated with moodle plugin available in moodle.org. When we test download recording button in modedit.php in moodle the download file is the html page login of openmeetings.
We're reviewed the coding in plugin for request download recording and it looks that the problem is the url used is:
gateway->geturl() /openmeetings/recordings/$type/$hash
When we use this url by own, openmeetings redirect us to login page.
We search for some change in this url (in version 3.1.2 at last was ok) and not find it in changelogs nor tickets.

Thanks by advance
