Can No Longer Find Local Server

I just logged into my XBO and attempted to watch a video located on my Plex server. However, I soon noticed that my Plex server, to the XBO, appears offline. I have confirmed with a friend who also has an XBO that he can see and play videos from his XBO to my Plex server. Locally, I can access my Plex server from everything (PC, Android, and Roku) except the XBO, which says that it is offline. I have tried logging out and back into the Plex server to see if that would resolve it (along with changing the security settings). I have also tried relinking the app. Is anyone else experiencing this?

Disregard this, I have figured out the issue. It was a firewall that someone was turned on.
