Almost give up... I cannot see my media server once I log in into my NAS Synology 920+

Hi everyone,

I almost give up trying to make PLEX working properly on my NAS Synology 920+. I tried almost everything, but I cannot access my server from my PC, Android, or TV.
In the screenshot, you can see what I see when I log in.

Settings which I already did 10 times: giving permission to plex user, same local IP on the server and on the PC. Port 32400 open.

Any suggestions??

Hi Chuckpa,

Thanks for your reply. That’s a super basic guide, I reinstalled and uninstalled at least 6 times, and still, I’m here.
I did it now again, I get this problem also.

Now I have to underline how before it was working, but since I raised the security level by activating firewall and other stuff, I cannot get in anymore.

Do you have any other idea to fix this?

Thank you for adding the details. I didn’t know where you were at based on the screenshot & info. http:// ip.addr.of.nas ? http://app.plex.tv ? (different results for each)

Given you have the Synology firewall on now,
-and-
are behind the firewall of your edge device (modem/router)

  1. Turn off the Synology firewall for now – we can activate it one step at at time.
  2. Stop Plex
  3. Install the Synology “Text Editor” app (Package Center)
  4. Control Panel - Shared Folders – EDIT the Plex share
  5. Give yourself R/W permission to it
  6. Now open File Station
  7. Plex / Library / Application Support / Plex Media Server
  8. Right click Preferences.xml → Open in Text Editor
  9. look in it for secureConnections="x" preference. (x = 0,1, or 2)
  10. I suspect you have it but this might just be a credentials thing.
  11. Remove the entire preference secureConnections="something" (carefully)
  12. Now we’re going to remove your existing ownership credentials and start over with them. I’d like you to, while here in the editor, carefully remove –
  • PlexOnlineUsername=“value”
  • PlexOnlineToken=“value”
  • PlexOnlineEmail=“value”
  • PlexOnlineHome=“value” ← you might not have this one and ok if you don’t.
  1. Now save the file.
  2. Go to any browser tab with Plex/Web open and Sign-Out
  3. Restart the browser
  4. Start Plex
  5. Wait 1 minute for it to start up
  6. Open http://ip.addr.of.syno:32400/web
  7. Sign in
  8. It will either want to complain immediately or be waiting for you to claim on the Settings - Server - General.

Warning

You must be on the same subnet with it to do this. (e.g. 192.168.x.x, 172.16.x.x-172.31.x,x, or 10.x.x.x) . Anything else is a guaranteed “No Soup” (not authorized). This is because PMS will not allow itself to be claimed “On a Different Network” (think of how a remote host/VPS operates and why it needs protecting. PMS is protecting your media)

Let me know how this works out?

So Chuck, really thanks again for trying to help me.

I followed all the steps, once I reach inside the preferences.xlm file, none of the above lines you mentioned were in the .xlm preference file. So I don’t have to remove anything there right?

What’s the next step you would suggest?

Oh I forgot to reply to what you said before.
The first screenshot is referring to the plex website when I try to log in there.
The second one is when I try to log in with my local IP.

Small update: I tried to run EMBY and everything works fine there…
Personally, I would like to use PLEX and not feel forced to change service…

Anyway, with this proof, I realized how the problem is entirely related to Plex and not my settings at all…
I have the feeling that PLEX doesn’t recognize me as the owner of the server for some unknown reasons…

@Vaddieee

What’s the IP addresses for your Computer and for the Syno?

Emby will allow non-RFC1918 addresses on your LAN because Emby doesn’t have brokered sharing (you are responsible for external access management).

Plex does require it because it needs to know if the address of a server or a player is on your LAN or is outside somewhere on the Internet.

@ChuckPa

Ipv4 of my computer is: 94.255..
ipv4 of my NAS is: 94.255..

So I guess everything is fine right?
This started to happen since I changed my password on my DSM account. Can that be the problem?
I’m getting extremely frustated, it’s sinced 5 days I’m trying to fix this without any luck.

EDIT: subnet mask same for both!!

No. Now I understand what’s wrong.

RFC-1918 = Addresses in the range:

  1. 192.168.x.x
  2. 172.16.x.x - 172.31.x.x
  3. 10.x.x.x

This is as defined here:

Are your machines directly connected to the internet or do you have a modem/router between you and the internet?

If you have a modem/router, AND your modem/router is assigning the IP addresses, then the solution here is straight forward. The solution is to make the DHCP server use any of the three allowed ranges.

Why is this necessary?

  1. RFC-1918 addresses are not routed on the Public internet. They are 100% within the confines of your home LAN.
  2. I can safely tell you my Synology NAS is 192.168.0.23 and know there is no way for you reach it.
  3. RFC-1918 addresses (NAT private networks) were created to help manage the shortage of IPv4 addresses worldwide. Multiple devices on the LAN share one public IP address.

Plex has built in protection to prevent a machine being “claimed” through the browser (what you’re trying to do) when it has a Public IP address.

How would you like to proceed?

@ChuckPa

Thanks really a lot for your reply.
My machine is connected through a router and they don’t directly go into the internet as u said.
I understand the problem but before I changed the password everything was working correctly even with this setting.

Anyway should I create a DHCP server from the Synology NAS configuration??
What do you suggest to me? Do you have a guide for it?
I really appriciate your help!!!

@ChuckPa

When trying to create DHCP on my NAS I get this message

dhcp
dhcp923×542 27.6 KB

It looks like you have DHCP running somewhere.

I am going to send a PM so we can look at your other IP addresses privately.
