I have some media files on my PC, but my Seagate NAS is my dedicated server. Sometimes one is reachable, and the other isn't. If I restart my router and NAS everything starts working again, but it's usually short lived. Within the next few days, again Plex isn't able to pull up any server. However, the Seagate Media App works and pulls up all the videos fine. I usually access the Plex apps on my Roku TV's.
