Plex Server Settings Disappeared - Asked Me To Create New

I’m still trying to determine what’s happening, so this may be a bit scattershot, but looking to see if 1) there’s anything known happening or 2) anything quick I can try.

I have a Plex server running on a Linux box (Linux Mint 21 right now I believe). Plex Server version shows as 1.43.0.10492.

Last night, I tried to pull up Plex on my TV, and noticed all of my libraries just had a Splat on the icon. I went into my Linux box and pulled up the Plex local host to go into settings and check things out. When I opened the page and signed in, it opened a page like a new server setup, asking me for a sever name. Interestingly, my current server name was already populated in the text box, so I assumed maybe some update or something and just clicked next. After that it asked me to start adding libraries. At that point I skipped though and got to the main settings page. That’s when I noticed that under Servers I now saw my same named server appearing twice. One was showing Unreachable, and the other was presumably the new blank one I just created. It looks like all of the Web and sharing settings are still intact, but I have no access to the original server in the configs.

I was still hoping for a quick fix (and it was late), so I decided to add my main movie library to the “new” server instance, which started scanning away (and is still detecting credits 12 hours later). But now I’m concerned if just rebuilding is the right course of action or if there’s something else I should check as to why the original server shows unreachable even on the same machine.

Edit: I pulled up the “new” sever just to see and sure enough the library is there, and interestingly enough, looks like it has the data from the old. So watched tags appear on movies that have been watched, etc.
