Impossible to launch Plex Media Server on Synology

Hello,

I’ve a big problem. I did the last update on my Plex server (v1.13.0.5023-31d3c0c65). I’ve always all my user and my account but when I logged-in with my user plex tell me => Search of a Plex server and download plex server.

So, impossible to have an access of all my libraries… When I go in Settings in my account, I don’t have “server settings” and this is the big problem I guess… because impossible for me to connect my Plex pass account with my server…

I did already a total uninstallation but no effect… I removed plex user, shared folder and all plex folders… always the same problem.

Somebody know how can I resolve this problem? Thanks a lot.


I did already this : forums.plex.tv/discussion/260226/upgraded-plex-now-unable-to-find-server

Please open File Station.
Navigate to the Plex share -> Library -> Application Support -> Plex Media Server
Right - click Logs and Compress to Logs.zip

Please attach the ZIP file here. I will look

here my logs, thanks

and here this is my logs after a complete new install. After wiping all data and folders

It’s definitely up and running.

Sign your browser out (upper right corner).
Open the IP address of your Syno http://192.168.1.120:32400/web
Settings - Server - General - sign it out and back in. (something went goofy with ownership)
You should find your browser also automatically signed back in

Hello,

Thanks for your response. Unfortunately I tried with another browser (if it’s a problem with the cache) but always the same…
I signed out the browser
Go to the IP adresse of my syno
I tried to go to Settings like you said but “Server” doesn’'t appear…
I’ve always the same screen with “server not found, download and install plex”… but plex is already installed…
It’s possible to download an older version of plex?? because before never had that
I become crazy seriously :frowning:

I would like you to try this. It performs a soft-reset of your PMS ownership settings.
It makes PMS forget you own it and you will claim it again. Something may have happened to that file when you upgraded.

  1. Stop Plex
  2. Open FileStation
  3. Navigate Plex/Library/Application Support/Plex Media Server
  4. Rename Preferences.xml to Preferences.xml.save
  5. Start PMS
  6. Again open http://ip.addr.of.syno:32400/web
  7. It will present you with the signin and setup screens.
  8. Start to perform the first-run setup but DO NOT create any libraries. Your libraries are already there and waiting for you
  9. Continue through the setup until you get to FINISH
  10. Arrive at the dashboard.
  11. Settings - Server
  12. Go through each tab and check each value for correctness

Like I said, I already did this instructions with your explanations here : forums.plex.tv/discussion/260226/upgraded-plex-now-unable-to-find-server/p1

My interface stuck always on the same screen

  • I tried already to remove the preferences.xml
  • I tried already to remove all the folders and reinstall all but I’ve always my user when I’ve reinstalled all. I don’t understand

Is there possible to have an older package installer? like v.12 instead v.13? I’ve a Synology DS718+

We will do it this way:

  1. Remove Plex from Package Center
  2. Control Panel - Shared Folders - Delete the Plex share
  3. Control Panel - Users - Delete the Plex user
  4. Reboot the NAS
  5. Install Fresh

already done 3 times yesterday before writing in this forum… always the same with always my user present in the system after a new fresh install. I guess if it’s not a problem because I do mirroring with my NAS?

Is it possible to obtain an older version for the package installer?

I think you have a NAS problem. I am the Synology developer so let’s jump into this deeper.

  1. Install the package again. If it fails to install, you have a problem with the NAS. DSM is damaged somehow. If it fails to start, we will continue with the next step below
  2. Control Panel - Terminal & SNMP - Enable SSH
  3. Control Panel - Users - enable the admin user
  4. Using putty or ssh connect to the Synology as user admin (the ssh command will be ssh -l admin ip.addr.of.syno)
  5. after logging in: sudo -su root to elevate to root privilege
  6. `cd “/var/packages/Plex Media Server/scripts”
  7. ./start-stop-status status
  8. ./start-stop-status start

report back your results. Screen shot or copy/paste of output are ok.

I did it for the fourth times… always the same.

  • I removed all folders and users like you said.
  • Restarted the NAS
  • And now I search on my package manager “plex” so I installed Plex for package manager and he give me the v1.12
  • So I installed it
  • connect to http://192.168.1.120:32400/web interface
  • the interface ask me to connect with my account
  • so I’m connecting with my google account
  • and tadaaaaaaammmm always the same screen at the beginning… The server tell me “no server installed, please install plex”

Here the result of the commands :

root@XXX:/var/packages/Plex Media Server/scripts# ./start-stop-status status
Plex is running
root@XXX:/var/packages/Plex Media Server/scripts# ./start-stop-status start
Starting Plex ...

perfect. As I expected. It’s already running… It’s what your logs previously reported as well.

Do you use the Synology firewall?

Yes, the firewall is activated by default
And I forgot to mentionne I’m not at home now (Tomorrow I’m at now in my network). I’m using a VPN now to do all actions to connect to my home network

@jonatrey said:

As trumpy has said. You must SSH tunnel through the VPN to complete setup again.

This is because PMS has default RFC1918 security. It cannot be ‘claimed’ (initialized) by any IP address not on the server’s local LAN (same subnet)

Okay, so I will try tomorrow at home. But yesterday I tried too with “teamviewer” in a computer on my local network. But just the first step => uninstall all and reinstall all. No effect.

So I guess it’s better to do a test tomorrow at home and I come back to you if the result change.

Thanks for your help, I come back tomorrow here.

Hello,

So I just tried in my local network to :

  • uninstall plex
  • remove plex shared folder
  • remove plex user
  • restart my syno
  • install fresh plex

Result : this is always impossible to have plex server setting available. I’ve always the same screen form my local network

But is there normal than after all steps (uninstall all, reinstall all) I’ve always my two login for plex present??

IP address of your computer?
IP address of the Synology?
Are both in the range of:

  • 192.168.x.x
  • 172.16.x.x -> 172.31.x.x
  • 10.x.x.x

If not, you must change the LAN or use SSH -tunnel. PMS is configured for, and requires, RFC 1918 LAN network addressing.
