I thought the issue was being caused by multiple hard drives on my PC, so I went out and got a 6TB, moved all my content over to that, and reinstalled PLEX Media Server. The problem still persists, where the server just stops running after about 45 minutes.
When I get home, the little icon in my system tray disappears when I mouse over it. And shows will freeze when the server goes down, and will usually un-pause fairly quickly after I re-open plex media server.
Have you tried messing with any of your windows Power settings?
If not, try this: Go to Windows Settings>System>Power & Sleep on the left panel, and set both to “Never”. Then go to ‘Additional Power Settings’ on the right and set it to High Performance. See if that corrects the problem
What else have you tried so we’re not going over things twice? I’m assuming you’ve uninstalled and reinstalled the server and set it all up again fresh and it’s still happening? Anything else?
