Xbox one Plex not able to connect to server without internet?

My internet went out last night and Plex on the Xbox won’t find a server now. All my other devices, apple devices and computers still connect but not Xbox. Is it reliant on the internet to access the server? Any help is much appreciated. I am running the server on both a drobo and computer.

So looking at other posts I noticed the account username and email were undefined. I try to sign out but then again I don’t have internet so it really won’t work then. If I hotspot from my phone everything works. So I assume you can’t use Plex on xbox1 if you don’t have internet, regardless if it is on the same network… they really need to make it a server.
