Server not found, Diskstation not authroized

Plex Media Server NAS & Devices
1

OK, I am at a complete dead end. I have read virtually all the support posts on solving the issue of “Looking for Servers…” after a new install on a Synology 716+II NAS drive. I tried installing Plex from the Package center, installing from a Plex.tv download and regardless of how I install the package and run the service I keep getting the same results: after logging into my PlexTV account following the launch of the Plex App from the Synology the browser just sits on “Looking for Servers…” endlessly and from the PlexTV App on my phone it shows “Diskstation” (my Synology NAS name), which is listed as a gray bar with the word “unauthorized” under it.

This is all on my local network. I’ve opened the router TCP port 32400 and attempted to connect using my externally available URL (using DynDNS) and my local IP address for the Synology. Results are always the same as described above. I “temporarily” subscribed to PlexCloud and that worked from my browser, Tivo Romio and Phone. The Synology is simply unreachable and that’s what I will use or just drop the PlexTV service altogether. HELP!

Step 1 after installing and starting PMS on Synology: Open http://ip.addr.of.syno:32400/web in your browser. Dont’ try to find it by name because it doesn’t have a name yet. This is why Plex/Web can’t find it. Complete the setup/first-run wizard and associate it to your Plex account. Once complete, it will always be there.

I read all the instructions and noted in my post tgat i did this already via the actual ip address on my network and the name.dyn.biz:32400/web. Both methods do not result in the server being found. thought it was a router port issue - 32400 open. Thought it was an install issue - uninstalled and reinstalled two different ways (via package center and via download). What am i missing???

4

I also tried the broadband ip address… also didn’t work. Uninstalled reinstalled… Been at this for days before posting here. Really no idea where to go next.

If you will forgive, I’m going to roll back to basics and share what I have in hope it will help communicate what I’m probably missing.

  1. The router at 192.168.0.1 (obvious ISP-provided router)
  2. Managed layer 2 switch for LACP (for the NAS) invisibly at 192.168.0.9
  3. Desktop system at 192.168.0.13 (where i’m responding from now)
  4. Printers at 192.168.0.14
  5. Wifi AP at 192.168.0.15 (wifi devices are given addresses in the .200 - .250 block should i ever need that many)
  6. Plex support computer at 192.168.0.16
  7. NAS at 192.168.0.23 (up and out of the way).

Notice the LAN is ‘flat’ and all key systems have a static IP address.

The Synology configuration: Standard box with the following networking:

  1. Ethernet ports 1-3 are ‘bonded’ as one port (I aggregated 3 for throughput) is static assigned to 192.168.0.23.
  2. IPv6 is completely disabled
  3. Ethernet port 4 is unplugged
  4. The firewall is not used / is disabled.

My Plex configuration:

  1. I created a manual port forwarding rule in the router from Exernal IP (WAN) side -> 36400/TCP port forwarded to 32400/TCP of 192.168.0.23 (where Plex lives)
  2. To install Plex cold it looks like this:

A. Package Center - Manual Install - giving it the .SPK file I downloaded from Plex
B. Let Package Center start PMS after installation is complete
C. From Chrome/Firefox, open http://192.168.0.23:32400/web
D. Greeted by the startup wizard and sign-on
E. Walk through, creating one Library, ending up at the Dashboard.
F. At the Dashboard, Settings - Server - Remote Access
G. When I first enable it, it will attempt to find a way in but will fail. This is expected and how I want it.
H. I check the box to Manually specify port and enter 33600 then retry and save.
I. All is good

Now I can go to my other devices. In the time it’s taken me to complete this step, PMS and the devices have had time to find each other locally as well as through plex.tv.

My server can be ‘launched’ from Plex.tv or found by opening http://192.168.0.23:32400/web or just ‘http://hostname:32400/web’

Does this help?

Thanks for the details. Let me explain my process.

Router at 1xx.1xx.1.1 (custom IP)
Synology DS716+II at 1xx.1xx.1.50 and 1xx.1xx.1.51 with fixed IP addresses (not bonded as my router doesn’t support)

My Plex configuration process:
I created a manual port forwarding rule in the router from External IP (WAN) side -> 32400/TCP port forwarded to 32400/TCP of 1xx.1xx.1.50 (where Plex lives)
Deleted prior install, deleted plex user, deleted plex shared folder
A. Package Center - tried installing from within package center and tried installing from downloaded .SPK file I downloaded from Plex (got the same result below)
B. From Chrome I opened opened http://1xx.1xx.1.50:32400/web (also tried externally accessible address @ http://MyName.dyndns.biz:32400/web)
D. Greeted by Plex login screen and “Plex Pass” sales screen after login to purchase subscription.
E. Closed Plex subscription screen and browser sits with spinning icon and says “Looking for Servers…” and never reaches the point where the wizard asks to setup a library or anything.

I’ve been at it again today. I tried installing the PMS on my Mac and what do you know, it installed without issue. I moved the port forward to my Mac and remote access also worked just fine. The issue is, I need this running on my Synology where I have 6TB of storage and constant access.

I went through the “Read this first” post and tried everything there (actually very good post). Fully deleted PMS, went in via SSH to validate directories were gone, disabled the firewall on the Synology, enabled UpnP on my router, … still the same result - it never gets to the wizard for establishing directories, it just hangs at “Looking for Servers…”

Any other ideas out there or is there a number I can call support at Plex for help?

I have same problem: it never gets to the wizard for establishing directories, it just hangs at “Looking for Servers…”

I would like you both to do the following:

  1. Stop PMS
  2. Open File Station and navigate to the Plex share
  3. Drill down into it until you are in the Plex Media Server directory
  4. You will find Preferences.xml
  5. Delete it.
  6. Start PMS
  7. In your browser, navigate directory to the IP http://ip.addr.of.box:32400/web
  8. Give it a second and you will be greeted with the Welcome and Startup pages.
  9. If you get anything else, Please screen capture it and let me see.

I gave up and bought a Mac Mini to run as my Plex Server. No issues.

Happy to try and help diagnose to help others. After installing Plex on the Synology and it hangs looking for servers, there is no Plex share that is visible in File Station. The Plex share is listed when opening “Shared Folder” in control panel but not File Station. I had read the note on deleting Preferences.xml and deleted the entire Plex Share and reinstalled instead on prior attempt but that didn’t work.

Out of curiosity I used SSH to see what was in the Plex Media Server directory and there was no Preferences.xml. Here is the listing:

It’s good to see you have SSH command line access

Do the following as it will make your life a bit easier. (you have an older installation?) and make the Plex share visible.

sudo -su root
synoshare --setbrowse Plex 1

Now verify in Control Panel - Shared Folders your Syno username has read/write permission to the Plex share. FileStation will not let you see it until you do.

13

I can now browse the Plex Share and deleted the Preferences.xml file. Now it just connects to my Mac Mini, regardless of whether I put in the IP address of the Synology system. It never takes me through setup for the Synology Plex install. See the attached screen capture. That IP address shown is my internal network IP address for the Synology.

Once the Preferences.xml is deleted, you must use the local LAN IP (e.g. 192.168.x.x or 10.x.x.x) of the Synology to redo the setup.

What you show above is a Public IP. PMS will not allow ‘setup’ from a public IP (to prevent someone from hacking your machine when you’re not looking)

Actually, that is my local LAN IP. I would not publish my public LAN IP :slight_smile:

16

That’s the problem.

PMS only supports officially documented “Private LAN” address ranges. Anything else is considered to be a Public (non-local) address.

17

Well, at least now I know. My new Mac mini is running great so that’s where Plex will stay. Thanks!

18

Just wanted to say thanks, for weeks I have not been able to use plex after I had installed google wifi which caused/created double NAT and somehow Plex wasn’t accessible anymore…
anywho deleting the pref.xml worked but instead going through the browser and typing the IP which didn’t work, I clicked on the link in Synology under packages/Plex

19

I’m glad the link in Package Center worked for you. I put it there as a quick reference.
Whichever you find easiest to use is ok with me. :slight_smile:

Plex won’t recognize any internal DNS/TLS you may have setup - so you’ll have to use the explicit IP address to get the setup to work.
