AccessDenied while trying to download the Mac installer for Unity 5.1.0f1 and 5.1.0f2 from the archive

Hi there

I’m trying to download the Mac installer for Unity 5.1.0f1 and 5.1.0f2 from the archive. I’m getting an xml error:

AccessDenied

Access denied.

Anonymous caller does not have storage.objects.get access to the Google Cloud Storage object. Permission ‘storage.objects.get’ denied on resource (or it may not exist).

I’m getting the same result whether I try Unity Installer or Unity Editor. Tried with Unity Hub and I got this error:

Unable to install. The Hub is unable to recognize this archived editor version. Please try again later.

Can someone check it out?
