Question about 404 errors

I was just wondering if there was any system in place to let people request files to be uploaded. For example, I’m trying to find this paper here: [Sci-Hub | Starvation Diet: Coping With Shrinking Budgets In Publicly Funded Mental Health Services. Health Affairs, 28(3), 667–675 | 10.1377/hlthaff.28.3.667]( but it says 404 not found. Anything that can be done about this? Thanks
