sub server without www "page not found"

hello

i have several sub servers under 1 domain. They all work fine.
However today I made a new one and this works fine too except it can not be reached without appending www before it.

I have not changed the templates or anything else so it might have to do with my browser/isp/location, i do not know.

Is there a way to check this? Directives in Apache are good, dns is good etc. that's why Im a bit stumped.
I can send the domain in question over email as i dont want it listed here.

thank you
ronald
