Moved server to new location/router

Plex Media Server NAS & Devices

Server Version#:1.25.9.5721-7
Player Version#:??

I’ve moved to a new location and the ISP uses a non-standard IP configuration (10.0.0.*) - I’m hoping this is the root of my issues. Prior to the move, Plex worked perfectly. Looking at the drive content (Synology DS218+), it appears that all of that as well as the media server program files are in place. I can access them through the Synology browser interface as well as through a mapped drive on my PC.

However, I cannot access any of the media when logged into Plex on a streaming device (Roku, smart TV, etc). No data other than the free Plex “TV” and movies are available. Permissions should not have changed, or have any affect on access just because of a different IP address.

I’m hoping that it’s a matter of having to reinstall or manually configuring the Plex Media Server software on the NAS. When I try to (manually) install server to the most current version, however, it gives me errors. I’m not sure how to check my DSM version, but I’m 95.87% sure I’m on v7.

If I try to install a v7 package, I get “not supported on DiskStation or incompatible with current DSM”.

If I try to install a v6 package, I get "This package requires DSM7.0-40000 (Update 0) or older) error. If I had DSM v6, that should (I think) allow this to install.

But, I also notice that DS218 is not listed in any package name.

Thinking that the DS218+ was just too old, I looked at replacement 2 bay Synology systems - and the 218 is still available, so I’d think it would still be a workable platform - and I’d rather stick with the NAS I’ve got if possible ($$$).

So, I’m not sure how to proceed from here. I’m fearful of reinstalling Plex from scratch for fear of wiping my media (14tb). But that’s the only other thing I can think of which might “re-connect” the server to the outside world.

Corollary questions;

  • If I did get a new NAS or wipe and reinstall my 218 from scratch (on a new/different drive), would I be able to access the current media content and transfer that to the new drive, or is it “slaved” to the current NAS and adding it to the new platform would initialize it as a new server pool (and empty)?

  • If I replace or reinstall my NAS Plex Media server, would I be able to restore the media from my backups (from current platform)? I saw an earlier post on this and it appeared that you have to really force it (I’d be afraid of breaking a link again).

  • If I install Plex from scratch (uninstall from NAS then manually install), would that alter any of the media content?

Thank you in advance.

Found the DSM version - 7.0.1.42218

Net 10 is part of the RFC-1918 standard for home/private networks, the same as 192.168.x.x or 172.16.x.x - 172.31.x.x addresses.

Make sure the default gateway, netmask, etc are correct. In Synology DSM Control Panel → Network, check both the General and Network Interface tabs.

Consider using a public DNS for the NAS, such as 1.1.1.1 (Cloudflare); 8.8.8.8 (Google); 9.9.9.9 (Quad9); etc. They are generally more robust than ISP DNS servers, which sometimes have problems resolving plex.tv hostnames.

Make sure the NAS can communicate to hosts on the Internet.

  1. Login to the NAS
  2. Control Panel → Regional Options
  3. Make sure the time zone is set correct
  4. Choose to synchronize with a NTP server, pick a server, and choose Update Now.
  5. If successful you will see Status = Normal.

That tests that DNS is working correctly and the NAS can communicate with hosts on the Internet.


After checking the above, try accessing the Plex server directly.

Stop Plex Media Server, wait one minute, then restart Plex Media Server. Wait ~2 minutes for Plex to completely start.

From a PC on the same network as the NAS, point a private/incognito browser window at the IP address of the Synology, http://syno_ip_address:32400/web (Do not use app.plex.tv, the “Open” button in Synology Package Center, etc).

For example, if the IP address of the NAS is 10.1.2.3, you would use http://10.1.2.3:32400/web.

Can you login to the Plex server?

For future reference

DS218 = ARM64 (ARMv8)
DS218+ = Intel 64 bit (x64)

Thank you, Chuck. That let me update the SPK (218+). I thought I’d tried that before, but obviously not.

That didn’t work. I’m sure it’s because my new ISP uses a non-standard IP base :frowning: But, even redefining the server didn’t help. So, I purchased a new drive and started from scratch. Transferring the media to the new drive was tedious, but it self configured with the current (assuming I’m correct) ISP router setup.

I need details please.

  1. First 2 octets of the IP address the ISP assigned you.
  2. IP address(es) of the Syno
  3. IP address of the computer you’re using
  4. IP address of the modem/router

ISP - 10.0 (Before move, 192.168)
Synology - 10.0.0.250 (Assigned, not dynamic) (Before move,192.168.0.250)
My Computer - Currently 10.0.0.39 (Dynamic, so that could change to reboot of router or PC) (Before move,Dynamic as well)
I don’t wish to provide the modem Router as that’s access address.

However, I’ve got it working (well, except for Dharma & Greg not being recognized - different post)). I’m 100% sure the primary issue was the ISP’s non standard local IP config (10.0, not 192.168.). I have moved my router to 1 other location in the past and had no issues - that ISP also used 192.168… So I’m sure it shouldn’t have had any problems from a simple ISP change.

I’m 95% sure I couldn’t “reconfigure” Plex to the new address because of a stray configuration file or some-such I didn’t remove when uninstalling and re-installing, especially as starting from scratch had no problems an Plex works as beautifully as before.

I just wanted to let you know how I got it to work. And, as it had been a while since your post, I thought it was rude not to respond.

That you for your help on this, and other, topics. I apologize for the tone of my post just prior to you last - I’d just got back from yet another procedure. :frowning: My Plex is my security blanket as I can’t read when on heavy pain meds or sedatives. :slight_smile:

Have a great weekend!

I totally understand. I’ve had more than a few procedures these past few years and there’s nothing like playing an old favorite movie to calm down and relax.

I was asking because the process of changing modem/router IP’s is straight forward

  1. Plex will only have IP addresses in Settings - Server - Network - Show Advanced in the “Allowed without authentication” and “Local LAN” blocks. Even with old/bad addresses there, you can always sign in if Plex can talk to the modem/router ok (which the Syno manages)

  2. Whenever moving to a new location / changing modem-router,
    – Get the new IP address (Gateway address) the modem router provides.
    – One by one, open your devices and confirm
    — The gateway address
    — The DNS address and/or 8.8.8.8 (google) as fallback

  3. After all the addresses are confirmed, Restart PMS so it sees the new environment.

  4. Now you go into PMS’s network configuration and adjust the “Allowed without auth” section if you’re using it.
