Content breakdown is only showing HTML

Hi,

I have setup a private instance on a VM (windows 10).

i have noticed that when i access my webpage on a test server, it only shows HTML. but when i try to test this same webpage on www.webpagetest.org, it shows css, js and other.

Also,

i cannot see a video and speedindex when testing on my local wpt.

Can you help me on this one? thank you
