That file, being over 5GB, is likely to be hitting some server side limits.
It could be taking too long, so that would be max_execution_time. It could be too large for the server to receive, so that would be upload_max_filesize and post_max_size.
There's likely other limits too. Aside from anything, is it even legal to redistribute that file? Being that it looks like it's a Windows 10 ISO. (I appreciate it's probably available as a free download in some circumstances, but that doesn't necessarily mean it's legal for you to redistribute it).
