Upload breaking halfway through
 

I've tried to upload a video like 3 times now, each time I get this error page halfway through, using firefox:

The connection was reset

The connection to the server was reset while the page was loading.

* The site could be temporarily unavailable or too busy. Try again in a few moments.

* If you are unable to load any pages, check your computer's network
connection.

* If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.


This site is permited access to the web, there should be no problem idk what to do.
