I installed a new router and now Plex cannot be found on my NAS Synology system

Plex Media Server NAS & Devices

PLease help me! My Plex media server cannot be found at all. I can still stream on my local TV and iPhone, but when I go to login to the server to check it, it says the server cannot be found. I don’t know what else to do!?

Server Version#: 1.21.1.3876-3c3adfcb4
Player Version#: don’t know what this means

  1. Open your browser
  2. Open http://ip.addr.of.syno:32400/web
  3. Are you and it both on the same (New?) subnet?
  4. Does it load the plex/web client – or do you get a blank/error page ?

If it loads, Plex is running and needs to sign into Plex.tv again to satisfy Plex/web.
This is usually networking setting in Control Panel - Network Interfaces - DNS and Gateway addresses. Make sure they match what the new hardware is using.

You can always stop Plex, go to file station, plex share, drill into it , right-click Logs -> Compress to Logs.zip and attach that ZIP here.

It opens, but now my server doesn’t show at all. I did remove it now because I thought that would allow me to add it again. Now it doesn’t even show a media server.

4

I don’t see any place for a drill into and any logs

5

I can’t even add my media server back to Plex now

6

I am referring to opening the Synology directly ( http://ip.addr.of.syno:5000 )

Open File Station.
If you do not see the “Plex” share – Control Panel - Shared Folders - Plex share - EDIT button - Permissions tab - Give your username R/W permission – save/close

Now observe “Plex” in file station.
Drill down through Library / Application Support / Plex Media Server.
Right click Logs -> “Compress to logs.zip”

Logs.zip (997.6 KB)

I don’t have the option to even add my media server back to Plex. It’s like it’s all gone. How do I add the media server back?

11

slow down… breathe.

  1. open app.plex.tv in the browser page.
  2. Immediately Sign out (upper right corner – click the Avatar)
  3. Now open http://192.168.1.240:32400/web (the IP address of your server
  4. It will want you to sign in. – sign in.

If you do not get it that way then continue below

  1. Sign into http://app.plex.tv again
  2. Settings - Authorized Devices - Server (dropdown)
  3. Remove (X) your Synology server.
  4. Don’t worry. We will bring it right back when PMS restarts.
  5. Look for other instances of your server there (Plex.tv might have a duplicate because of the networking change). If you see another, remove it too.
  6. Now sign out again.
  7. Restart PMS in Package Center.
  8. Open http://192.168.1.240:32400/web
  9. Sign in and “claim” if it asks you to do so.

I started moving all my files to a new share and an want to install Plex completely from scratch to see if that fixes it. I can try that after the Library folder is moved. Trying to save some Metadata

13

That didn’t work either. It tells me the address isn’t hosted but it is and theres no server for me to claim

14

“Isn’t hosted” is expected. It’s because the IP address changed. Your browser doesn’t have a token for that IP yet. That is your server talking to you.

That message is telling you: "This is someone’s private server (YOURS) not Plex.tv "

15

As for you fixing the files problems.

Your logs clearly show you didn’t give user Plex permission to read them. That’s all.

I figured I’d wait until you got control of the server again before tackling it.

If you want to start completely over. I will give you the instructions.

16

ok so that’s not scary, but still no media server is showing up. No option to add one or anything. Like I said I will start from scratch. The Plex thing read/write thing is every time I do an update I have to manual go in and give Plex read/write access, so I probably didn’t reset it after the 3rd time I tried to reinstall the PMS

17

Let me ask…

Are you putting your media IN THE PLEX SHARED FOLDER ???

18

Yes that’s where it has been since I created the PMS it’s been like that for over 2 years now.

19

Didn’t bother reading the warnings I put there?

20

So I’m guessing the Media doesn’t go in the actual Plex folder?

21

No. That’s for the app only. It was necessary to put it out there because DSM doesn’t have a large storage area by default. I needed something persistent which had space so I chose to use the main volume.

To clean this up –

  1. Move all your media to new shared folders.
  2. Delete the Plex share (Control Panel - Shared Folders)
  3. Delete the Plex user (Control Panel - Users)
  4. Uninstall the package.
  5. Restart DSM
  6. open https://app.plex.tv → Settings - Authorized Devices - Server
  7. Again make certain your DiskStation server is removed.
  8. Install Plex on the DiskStation
  9. It will create the shared folder again and the plex user.
  10. Give it a minute to perform first-run initialization
  11. Open http://ip.addr.of.syno:32400/web
  12. Sign in and claim it.
  13. Skip over adding sections for now. Let’s get it initialized. You can create library sections in a moment.

For each media shared folder:

  1. Settings - Control Panel - Shared Folders
  2. EDIT the shared folder containing the media
  3. Permissions tab
  4. Give user plex permission to read it.
  5. Save the changes.

After this is complete, return to Plex.
You can now start creating new Library sections – referencing your new shared folders.

Install the package. It will create a new Plex share and Plex user.

Here is the How-To.

Alright I will test this out in the morning. Hopefully this works and isn’t the new router that’s still causing it. I will let you know what happens and what I find. Thank you for the hard work.
