Why are my forms not loading when I click on them?

I am trying to open some pdf documents that I uploaded to an application, but it is not working. It just says "404".

Hi Cassandra, thank you for reaching us.

It appears you are trying to access your uploaded file within your submissions. The ability to view your uploaded file will depend on the form creator whether they would allow other users to view their uploaded files. We suggest trying to contact the form creator if you would like to access your uploaded file.
