Proof uploads fail constantly with mp4s

[JasonMa15]

 I can't upload anything. The progress bar will start for a few seconds and then fails. Then maybe a few more seconds. Then one second, etc. Does not matter what the file size is. I have to try each file 10, 20, 30 times before I'll get lucky and it'll upload all the way.

I would have your system admin or ASC (approved support contact) submit a case to Workfront's Support. Some troubleshooting steps you can take as well, are to clear your cache and cookies, or try a different browser. As a final resort, you can also reset your user profile (this probably won't help anything but it's sometimes worth a try)
