Install High Sierra HTTP error

I need some help. I have been struggling all day with getting this installed (sent to) self service, etc. I did the policy correctly I believe in JSS, scoped it out to my devices. Can see it in self service. It executes and downloads. Then immediately throws an error and does not show up in the applications folder. I looked at the log files and this is what I have, see attached screen shot. I poked around the discussion board and someone mentioned a solved case similar to this, it said to go to Library/Application Support/Jamf/Downloads and see if there is a partially installed app there. Only problem is, the downloads folder I do not have access to. Thoughts?
