Plex Thinks Local Devices are Remote

Server Version#: 1.43.1.10611
Player Version#: 4.159.0

My local plex server thinks that all of my devices that share a wifi with the server are remote. I do not have paid plex options so I don’t have the LAN options. I have tried changing the IPv4 and IPv6 settings too. Does anyone know what the issue could be?

This guide will give you some pointers on what might be causing local devices to be considered remote.
