Error 413 code when uploading large files by website

Hi, Need some help here.

I have a new installation of v6.0.2, upgraded to 6.0.8 on debian 8.

I tried uploading small files (75MB, 35MB) via the website and it is successful.

But files larger than 100MB fails with ‘Unknown error’ . From chrome console - ‘Failed to load resource: the server responded with a status of 413 (Request Entity Too Large)’

I got the same results on chrome, firefox and edge.

port = 8082

separate post as I can only paste 2 links.
