This is the closest thread I’ve seen to the issue I’m having–maybe not exactly the same but it has to do with a missing server. Not sure if I should start a new thread on this or not. Let me know if I should. For now, I’m just going to describe my issue:
I bought a new mini-pc a couple weeks ago as my old desktop had an unrecoverable hard drive fail. Had to do full new install of a Plex server running on Windows 11 Pro:

I set it all up using the computer name “806SER6” and realized that Windows was mirroring my wife’s laptop (she and I were using a shared Microsoft account) and I didn’t want to mess anything up on her end, so I created a new local account on my mini-pc that I could use. Not long after – and I’m guessing that local account is a factor here – Plex couldn’t find my library. I was stumped and didn’t know what to do, so I looked and noticed that Plex was trying to locate a server called “DESKTOP-CI6JOPN” something or other.
To fix, I re-re-named my desktop as 806SER6, thinking that might allow Plex to see the desktop (note: I thought I had already renamed the desktop as soon as I set it up, prior to setting up Plex server but now I’m not so sure).
OK all that said… here’s the problem. Now I have a Plex server running and two instances of 806SER6. It can’t find the first instance (which has all my media on it, file metadata edited and just like I want it), and a second instance (which is the quick version of my media without any edits yet b/c it takes a while to manually edit and I’d rather just get my old instance back.
After reading this thread, I logged into the shared Windows account, closed the Plex server instance and logged out, and came back and logged in/out and back into the local account. But still the problem persists:

Attached are my server logs.

Any help here would be hot. Thank you!
