I have 2 media libraries in my home network one on my PC and one on a WD My Cloud Home NAS connected to my router/modem. Sometimes I can see both libraries however after a dayor less one library becomes unavailable. Sometimes the PC library and sometimes the NAS library. I have set the NAS with a static IP and pinhole access via 32400. The PC has a static IP also. I can see both libraries when I open Plex on my PC right now but when I use my mobile phone on wifi I can only see the PC library at present. Any suggestions welcome.
