Improve error messages when an upload fails

[homonecloco]

I'm uploading a large batch of files, and most of them are working fine. However, now and then get the message:

Something Went Wrong
For some reason this upload failed. Please try again. If you are using a laptop, make sure you leave the lid open and adjust your settings to prevent hibernation. If this problem persists please contact the administrator.

I would like to know which is the fail that failed uploading. Since I have several files in the upload queue, it is hard to track down the culprit.
Ideally, I would like to have a list of all the files that failed to upload them again.
