Cannot download Installer.php

Hi,

I’ve been using duplicator for months now and it was working great. It helped me to have a decent workflow to refresh data between my PROD and DEV environments.
But now, I’m facing some problems with it. I can still create my packages but I cannot download the installer.php file anymore. This has started to happen about 2 weeks ago. I’ve tried from an OSX and Windows computer, thinking that the problem might be related to security and file download but the same happen on both systems. The download stops after 130Kb stating that the connection has been lost.
I’ve also updated duplicator to its latest version, uninstalled and reinstalled but I still have the same problem.

Any idea where to look at?
Thanks
