Can't Claim Server - Synology DS918+ NAS

Please help. I have been messing with this for days now. Here’s where I’m at…

I’ve been trying to install Plex on my new Synology DS918+ NAS. I have downloaded the Plex installer for Synology NAS (Intel 64 version).

I manually install in DSM. I give the Plex folder and my user folder read/write access. I open Plex and sign in. When loading Plex for the first time, it finds a new server asks me to log in and create a name. It freezes here and will not continue past this screen. If I reload the page it takes me to Plex homepage with an orange bar at top acknowledging an unclaimed server so I hit “claim it now”. When I try to claim the server, it times out and I get a notification that an update is available and “please install manually”. So the cycle begins. I have tried multiple times, each with a fresh install of Plex and the install file downloaded from Plex website.

Other notes…

  1. I’ve changed the trust level on NAS to any publisher
  2. Added Plex’s Public Key to the NAS certificates panel
  3. I do have Plex Media Server installed on the computer I am woking on but it is not running.

Please help!

One of two things has happened:

  1. The most common reason for failure is because the Synology can’t connect to the internet properly. (PMS needs the internet to be claimed)
  2. The less likely is you started the setup process before the NAS had completed the lowest level initialization. It doesn’t happen often but it does happen.

To remedy this, first check the network

  1. Stop PMS in Package Center
  2. Control Panel - Network - Network Interfaces - Edit whichever one you plugged in.
  3. Below is a screenshot of my Synology configuration. Your configuration will differ but should look similar.
  4. If you change any network settings, restart PMS in package center and attempt to claim again

If not a network configuration issue, then it’s an initialization issue

  1. Control Panel - Shared Folders - Edit the Plex share - Permissions - Give your username R/W permission
  2. In File Station open the Plex share
  3. Right click Library and delete it
  4. When it completes, you can close File Station
  5. Start PMS
  6. Wait 30-45 seconds as it creates all the low level data structures
  7. In a fresh browser window, open http://ip.addr.of.syno:32400/web
  8. Sign in normally (this will claim it for you)

If anything fails, I’ll need to see the logs

  1. Stop Plex
  2. File Station -> Plex -> Library -> Application Support - Plex Media Server
  3. Right click on Logs
  4. Compress to Logs.zip
  5. Please attach that ZIP file and I will find out why PMS isn’t starting.

Thank you, @ChuckPA – Working through this now. Thank you for you patience as I am a novice. How can I check if my own network settings are correct? I do not see your screenshot. I have a “default gateway” address and then “manually configure DNS server”. I have attached the Logs file. Thank you!

The best way to check the NAS settings are by comparing with your computer’s settings.

Both should have the same DNS server and same gateway IP addresses

Thank you and sorry it has taken so long to respond. Ended up going to sleep last night (much needed) and went to work today. So my default gateway address matches my IPv4 address. My DNS address however does not seem to match anything. It looks generic but my router does not have any DNS configuration options. It is an AT&T fiber router/modem that was just installed. Model BGW210. Did my log files seem fishy at all?

since you don’t seen to have a DNS value per se, Point your NAS DNS to the same IP as your AT&T gateway.

Holy crap, that worked! THANK YOU! Had a feeling I was missing something simple like that. So are their any risks/security vulnerabilities setting it up like this?

Nope. Their junk is between your junk and the internet. All still :+1: :smiley:

Thank you so much! So Plex is now available in network but still not available outside of network. Any thoughts? In the Remote Access tab, my Private address is green but Public address is red.

ISP modems are a gamble. Always are… Let it sit a while.

If it doesn’t enable… Sign into it and verify UPNP is enabled. (restart modem if necessary) then have PMS retry. It will find its way… eventually

Hi @ChuckPa,

I have the same issue, I have been trying to follow your steps but no luck here.
Can you please help?
I can’t see the attachment you mentioned previously.

Thanks in advance
