Error on update

Hi I'm getting the message to update to 3.13.3 but when I try to update the OSP package I get the error: Error connecting to server:403
I also get the message to download manually using the link www.joomdonation.com/index.php?option=co...ckage&document_id=91 but I get a 403 error there too.

I have generated a new download ID and entered it in my OCP properties but it changes nothing.

Thanks for your help.

Hi Justin,
Have you registered a Download ID through this link: www.joomdonation.com/download-ids.html and enter it in OS Property Configuration > Tab: Download ID.
And have you published the Joomla Installer plugin: OS Property - Update package
Thanks
Dam

Yes I've done that and checked the Update Package is published, I still get the errors (see attachment).

Thanks,
Justin
