Plex is lagging, and OMV doesn't show up on network.

I have several problems going on, the first is OMV doesn't always show up in file explorer, sometimes I can refresh file explorer and it'll work, sometimes I have to reset my server and it'll show up. The second problem is I have a Samsung blu-ray player which will usually detect the server, but when I got to it and pick the movie folder or tv folder, it will just give me the loading icon, and will not do anything else. I have gotten it to work, the other day I put several movies on it and tv shows, and I watched a full season of Game of Thrones with no problem. I get on there today and it keeps freezing up, and when it does work, the new movies I've added to it don't show up, even though I can go to file explorer and see them in the Plex folder. Any suggestions would be helpful, but after all the trouble this thing has given me, a replacement in software might be the best way to go.
