Media files not there

its local network, i created a user called home and when i try to use that sometimes it will say media not there even though its in the server, i also notice that the new movies are not there, it seems like the profile is stuck and never updates to the server, pls help, sometimes i need to clear cache of the app or reboot the media player or both but sometimes that does not work, no issue on when im on the server and playing the same movie, only happens on the app, using firestick and another tv is nvidia shield

I might have figured out the issue, i upgraded to a new computer and transferred the plex server to the new PC, i think the old PC has plex server on startup so in my network it shows 2 plex server same name going and this might have confused the app, i made the necessary changes, hopefully this fixes my issue
