[Help] Plex won't enable after cheating on the TOS Plex app with a plex docker

I was trying to set up a Tautulli docker container to be able to see the usage stats for Plex (installed via TOS 6 app). I was following some guides and i accidentally created a temporary “test plex” docker because I couldn't figure out where the logs where at the time, which i think messed up my actual Plex App. Even after removing the test plex docker, my Plex App would no longer start.
I’ve deleted as much of the plex folders that i can and have uninstalled the Plex via TOS 6, restarted the NAS, then reinstalled the Plex via TOS 6 but Plex won’t enable/start. After that I backed up my plex library and configs elsewhere and tried deleting ALL the Plex and did the whole thing again, Plex still wouldn't enable
Used chatgpt and it’s saying to do a clean start for the plex app by removing the hidden users/groups leftover from the previous install because it could be messing up the permissions but I don’t have root access to do so.
Here's the hidden users and groups after i uninstalled Plex and restarted my NAS. Can't figure out how to log in via root to delete them:
Code: Select all
NAS@F4-424:-# grep -i plex / etc/passwd
plex:x: 10001:1003:TOS App User: /home/plex: /bin/bash
NAS@F4-424:-# grep -i plex / etc/group
video:x: 44 :plex
render: x: 109 :plex
plex:x: 1003:
NAS@F4-424:
Am I on the right track? Any suggestions on how to fix my Plex?

Please check if the default port 32400 is being used by any other processes or services.

I'm not the OP, but how would I go about checking within the Terramaster Terminal what ports are being used by PLEX?, what are the terminal commands, please.
I'm having trouble setting up two PLEX NAS servers, One is for Plex TV SHows F5-422 and the other for Plex Movies F5-221.
PLEX movies is 32400 public, but when i set the PLEX TV Show server to 32400, one of servers loses remote connection.
So, I've set within PLEX the TV show Port as 32401, now some of my mates can't connect to the TV server.
Is there a way for me to check within the Terramaster terminal to see if there's a port issue and change the port on the TV server to 32401.
thank you
P.S
Not sure if this needed to be a new thread or if i could ask here, seeing as its about plex ports

Hi.
You can check port usage here: TOS > Control Panel > Ports. You can also log into the terminal and use the netstat command for more details.
If your two NAS devices are on the same network, then generally the external port 32400 cannot serve two Plex Servers simultaneously.
Based on your description, we cannot yet guess the specific situation. We hope you can troubleshoot successfully.

Hi, there
You can check port usage here: TOS > Control Panel > Ports.
Not sure where that is, but maybe it's because my NAS are the F5-221 and F5-422 and the lastest TOS installed is 4.2.40. When I click apply to see if there are any updates, its keeps telling me I'm running the latest version, so maybe this is why I don't see "Control Panel > Ports" ?
If your two NAS devices are on the same network
Yes, Both Plex servers are using the same network, one is running solely for movies and the other for TV shows.
I would love to update to the lastest NAS, TOS, but, if I understand, I must back up all my 5k moves and over 499 tv shows before attempting to an upgrade. Sadly, my whole collection is around 40TB and I don't have the spare storage space to do a complete backup prior to attempted upgrade.
Unless I can upgrade without losing my Media collection and the RAID 5 array they are both set up as?
P.S
If you prefer I make a new thread, please let me know
Thanks

If your question has little relevance to the original poster, it's better to start your own thread.
If your NAS is running TOS4, and you don't have a special need for new features, you might consider staying as is because the upgrade process can be quite cumbersome.
Regarding the issue with two Plex servers, based on your description, it seems they cannot share the external port 32400 simultaneously. This should not be related to the port configuration of Plex on your NAS. If you still want to check, you can log into the terminal and use relevant commands from the netstat tool to view the details.

I've no need for special features, I use my TerraMaster NAS machines solely for PLEX, one is for movies and the other for TV Shows.

You are correct, I was able to make the necessary adjustments on my new Flint 2 router, as the ISP router had a basic interface and features.
I set a new port for the 2nd PLEX port and all is good, just not happy with open ports,
lol.
Anyway, thank you for the replies and the link for commands and I'm sorry if i kind of hijacked this post
