So with your code.
1. The upload starts and is steady
2. 2 seconds go by and the progress bar appears
3. Shortly after upload and progress bar 'hang'
4. Progress bar reports upload failed
5. Upload resumes and finishes without hanging again.
I also added the new code to my test application in case you wanted to take a look.
