Yeah I just clicked the easy install button 10 months ago and it created all its folders successfully and installed successfully, but I never used it or connected any of the smart tv's to it. I haven't touched any of the HexOS stuff since the initial install, just have been using it as a NAS so there's plenty of files on my NAS. Today when I decided to actually use Plex I saw there was an update for Plex and tried to run that update, but that updated wanted the claim ID and when I put it in, the update would fail without creating any message in the notification. That's why I decided to uninstall Plex, which did create a notification that it was successful, and then tried to reinstall Plex, which is now giving those error messages.
I had thought to try and poke around TrueNAS to see if I could figure out how to give the group "Apps" permissions, but when I click TrueNAS and it goes to the IP of the server, that also comes up as can not connect in my browser... so that's another issue I'm trying to figure out. HexOS works fine though, and I'm able to access the NAS, just cant for some reason access TrueNAS either.
