What method are you using and what is the failure size? Have you increased the file upload limit size on your server?
Most are set at 2MB.

Hi Scott,

I have increased the file size limit at server side. I am using from.submit method to upload files at server side.

I was twice able to upload 250MB file, then i made some changes, now larger files are not been uploaded, smaller files had no issues though.

>>> then i made some changes
What changes did you make? Do you have a copy of the original to restore back?

Without knowing your setup, it would be difficult to say. How long does it take before you get the error?
Perhaps increase max_input_time?
