Server Config Files

I recently just signed up, and have been trying to find exactly where the config file for my server is. After looking in "Files" and getting a message saying "File not found." I was wondering if this is an issue going on at the moment, or if I'm just missing where the config files would usually be stored.

So just to be clear, is there no way to edit the config of the actual server file? Not a super big deal, I just wanted to mess with the idle time.
