Answer 2

According to here and here this kind of error is often caused by the filesize being too large. Try posting a file with a smaller size to confirm the solution works, then a larger file to reproduce the problem. Also, the second link contains a possible solution.

Answer 3

Retry with a small text file. If that works, it might be because of the limit of the file size set on the server.
