While I'm debugging my WEB Application; I encounter this error message on the browser if I upload one of my files: "The page cannot be displayed".
It only shows on the browser's page and not on the debugger.

I don't know why, I think it is not on the file size because it fails on the file with size of 9.03MB only but it works on the 23MB file.
It is not on the filename becuase I tried to rename it; I removed all the spaces but still fails.

What is the real problem?
