Multiple servers

Server Version#:
Player Version#:I have a Synology running Plex (native, not in docker), then I also have a Mac Mini with the media from the Synology nfs-mounted running it’s own Plex server. It’s worked fine, with two different Plex servers for a couple of (about 5) years. Now all of a sudden I seem to on be able to run one of them at a time. I don’t know if the problem is with my networking or somwhere with the Plex “networking” using the web/app interface on x.x.x.x:32400/web.

The native Synology instance is the one I used to share with my friends and family over the internet, while using the Mac Mini server personally (both here at home and over the internet).

I started looking at my router NAT settings and found that I’d only forwarded port 32400 to the Mac Mini - so I really don’t understand how it ever worked before.

Anyone who can help me troubleshoot this?

(edit, update) At the moment I seem to have 2 different Plex servers running, independently of each other. If I access one I can no longer see the other - before I could switch between them in both the web interface and the native Mac client (which I know is just a web view).

I’m now at a point where if I run the Mac Mini server only I can access it - but as soon as I start the server on the Synology the Mac Mini instance disappears from the list of available servers…

Right now, if I try to access the Mac Mini:32440/web - I end up on the Synology Plex instance, even though in the addressbar of my browser it clearly says {ip-of-mac-mini}:32400/web

I guess this is somehow related to the fact that when I login to my plex account all traffic is routed via plex.tv instead of going between my browser (or app) directly to the server on my local network…

And at the moment, the Mac Mini server is up and running - but not accessible.
In the Plex Media Server.log I see multiple lines of:

Sep 02, 2024 20:00:03.813 [0x700007fb6000] ERROR - MyPlex: Error 403 requesting XML from: https://plex.tv/api/v2/server/access_tokens?auth_token=xxxxxxxxxxxxxxxxxxxx&unknownToken=xxxxxxxxxxxxxxxxxxxx

How did you create that second server?
Did you use the “move install” procedure (migration)? This might include the machine identifier of the original server — hence if you start both, Plex considers them to be the same machine and only giving you access to one.

Pick one of the servers, stop it and remove the machine identifier related properties from the server config (MachineIdentifier, ProcessedMachineIdentifier).

  • On the Syno, this information should be stored in the preferences.xml file in the server data directory. Should be as simple as deleting those lines from the xml file with a text editor.
  • On the Mac, the data is stored in a plist file and can be removed using the related terminal commands (e.g. defaults delete com.plexapp.plexmediaserver MachineIdentifier)

How did you create that second server?

I just set it up as new, “next to” the existing server.

Pick one of the servers, stop it and remove the machine identifier related properties from the server config (MachineIdentifier, ProcessedMachineIdentifier).

I’ll try this and see what happens.
Thanks!

Ok - now my Synology-server spins up, just like before. But my Mac Mini-server reports it’s “Unreachable”…
And I see these errors in the log:

And now both servers are unavailable…

I’ve now come to a situation where my Synology server is accessible via local IP-address ONLY, and hence not from any app, only in a browser

8

Hmm, I can reach it from my iPhone app, but not from the Mac app on my laptop - but I can access it using the local IP in a browser… :thinking:

Turns out the problem was that my ISP, without informing us customers, had applied a NAT-layer in the network between internet and us end customers… Back online now.
