No internet

I have been using Plex for many years now and have been loving it. recently, my internet has been out at my house because of technical reasons. because of this, my Plex server is not running so well without the connection. I remember previous versions where it would work wonderfully without an internet connection. Is there any features that needs to be turned on to allow for its use without an internet connection? If not, can one be added so that it would work as well as it did when Plex first came out?

Thanks for the help that did the trick.
