Can't start plexmediaserver_plexpass

[Wisdom]

Holy cats this post turned into a dumpster fire! It's working, it's fine, the network just needed a minute to settle down. Hard refreshed and it's back, metadata and all. Sheesh!

Okay, I actually pointed out the problem to myself in this post - my user and group were still pointing to vanilla plexmediaserver, and needed to be changed to plexmediaserver_plexpass in rc.conf. However, now I've got network issues.

Alright, so here's the process: I started with a working 11.2 plex install. I was stuck on 1.16.something, and wanted to update. I've been running a plex pass for a while, and thought I should get on the right update track. At the same time, I wasn't willing to nuke it from orbit because I needed to keep my sweet, sweet metadata.

Stumbled over this post about how to upgrade. Followed along, worked like a dream - until the last step. Whenever I run service plexmediaserver_plexpass start it seems like it should be working, but when I check the status? Nada.

So, enter troubleshooting. Found this thread; ps auxw | grep -i plex gives me:

Code:

root@Plex:~ # ls -l /usr/local/plexdata-plexpass
total 9825829
drwxr-xr-x   2 plex   plex            2 May  2 23:53 Plex
drwxr-xr-x  10 media  ftp            11 May  2 23:55 Plex Media Server
-rwxr-x---   1 root   ftp   10069496409 May  2 23:44 plexbackup.tar.gz
root@Plex:~ #

I've quadruple checked that rc.conf has plexmediaserver_plexpass_enabled=YES. It also shows me that the plexmediaserver_user="media" and plexmediaserver_group="ftp" - I think this is unchanged.

Additionally, I've generated no new logs since starting this adventure. /usr/local/plexdata_plexpass shows no new logs, no new activity, nothing. Just looks like, to my eyes, a fresh install.

As an aside, it looks like the rest of my old install is still around. The .tar I ended up making, following the guide, takes up several gigs. Is that worth getting rid of, and if so, how's the best way to go about it? Also also, I think my old install is still around - /usr/local/plexdata still exists, and that makes me think I could switch rc.conf to the previous settings and run my old server in the meantime.

So, yeah. Kind of out of ideas, and google links to click on. Anyone got any ideas for me?
