Plex in DSM 7 doesn't detect my NAS

Server Version#: 4.59.2
Player Version#: I Cann’t find the player version

I have a Synology NAS DS1517+. I updatet my NAS to DSM 7 and I updatet Plex to the latest version of Plex, the DSM 7 version. Since then Plex doesn’t defect / find my NAS. I set the permissions with the System Internal User on the Plex folder.

How Can I Solve this problem?

Did you “Update” the package or “Repair” it?

No I reseted my NAS, because I couldn’t update my NAS to DSM 7. My NAS conflicts with third party software. That’s why I reseted.

Leg eens uit wat je bedoelt met “conflict”?

In DSM 7 drukt Synology nu een rode waarschuwing af op ALLE pakketten van derden.

We hebben PMS getest op elk platform waarop DSM 7 draait.

Als je meer kunt uitleggen, kan ik je helpen om het draaiend te krijgen.

Het pakket zelf zal berichten in het Nederlands afdrukken als DSM 7 is geconfigureerd voor het Nederlands, anders worden berichten in het Engels afgedrukt.


Please explain what you mean by “confict”?

In DSM 7, Synology now prints a red warning on ALL third party packages.

We have tested PMS on every platform which runs DSM 7.

If you can explain more, I’ll be able to help you get it running.

The package itself will print messages in Dutch if DSM 7 is configured for Dutch else it will print messages in English.

I tried to update DSM to version 7. That is not possible because I got the error message that MariaDB (a third-party app) was installed. I have tried to remove MariaDB. Unfortunately that was not successful. I got the error message that the package service could not be started. That’s why I submitted a ticket to Synoloy Support. They indicated to hard reset my NAS via the reset button. This will remove all apps. I did this and updated my NAS to DSM 7. That worked. Now I’m trying to install Plex. That also worked, but when I open the app I don’t see my NAS.

Thank you for explaining.

I just looked at your account. I see that the “DiskStation” server hasn’t been seen by Plex.tv in 22 days.

I removed that from the account listing (temporarily) so we can get you started up again

Please confirm:

  1. Your Synology NAS and your computer are using the same RFC-1918 LAN network (192.168.x.x, 172.16.x.x - 172.31.x.x, or 10.x.x.x ) ?

  2. If true –
    a. Close and reopen the browser
    b. Download and install the new packaging (2.0). it is more flexible
    c. If it finds your Plex data sitting on the volume it will do everything it can automatically if possible.
    d. If your data is in the Plex share, it will want to ‘migrate’ . I will assist with that if you need it.

  3. If not, we will need to Claim the server as a second step after it is migrated. We use the “Plex Claim Token” for that.

Please let me know where you are at in the process at this point and how you’d like to proceed.

1.Yes, I am using 192.168.x.x LAN Network.
2.What do you mean by new packaging (2.0.)? I cann’ t find it on the Plex site. I am using the PlexMediaServer-1.24.1.4931-1a38e63c6-aarch64_DSM7 package.
3.I installed Plex again. I used a normal installation the first time. The second time I used a token. Both options are not working. It says: You Donn’t have permissions.

Did you read my message?

I solved it. The solution was to go to http://192.X.X.X:32400/web. Then I can sign in with my Plex account and add the server to the account.

I have another question: How can I remove the collection from the libery? Plex makes automatically a collection. I don’t want that.

Thank you.

I have a last question. I have set that if Plex adds movies, Dutch subtitles should be downloaded. This does not work. Either no subtitles will be downloaded or English language will be downloaded

The settings were already good. It does not work. Mortal Kombat has French subtitles. I’ve already refreshed my library’s metadata


Then I have to manually set the subtitles to Dutch for every film. That’s a lot of work because I have a lot of movies. Before I had problems, the subtitles were automatically set to Dutch when I added a movie. I need to troubleshoot more.

@The_Raptor

Embedded or Sidecar subs?

Sidecar subs. The subs you can download in Plex.

I double checked with a team member on this:

  1. You choose/change the language on the window where you search for the sub. I assume it defaults to your account language.
  2. Subtitles are not saved alongside the media, but in the PMS data directory in a blob database.

It does use the account language by default. You can change that on a per item basis.

I am using already my account language, wich is Dutch. Now I have to change the language in Dutch per movie. That’s a lot of work.
