Local web page don't see the server, how is that possible?

Plex Media Server
1

I have a working plex server since couple years.
I did some cleanup on my server and after reboot plex isn’t working anymore.
Here’s the problem : Server is not detected (In the center of the page this is a link “Get plex media server”. What is really weird is that I’m accessing the plex web ui from the lan ip (xxxxxx:32400/web).
I’ve tried everything, load backup, fresh install, and it’s always the same thing, the web browser don’t know that I’m on the actual plex.

Is there a way to bypass completely the plex SSO system? Maybe that would be useful for troubleshooting.

Have you already checked this procedure?

Yeah, already check this.
Even with a fresh install it’s doing the same thing.

Here’s the content of my Preferences.xml file:

<?xml version="1.0" encoding="utf-8"?>
<Preferences OldestPreviousVersion="1.25.1.5286-34f965be8" MachineIdentifier="be553268-fd14-48e5-9675-8a5cc53105bc" ProcessedMachineIdentifier="6ecc2ef5bf3eb43cf8bf8d3c91f3f479532b7693" AnonymousMachineIdentifier="37962d26-1209-473a-a204-3aee21caea62" MetricsEpoch="1"/>

LAN IP of your server?
LAN IP of your computer?

Are both on the same RFC-1918 subnet ?

Are you accessing / setting it up by Name or by IP ?

Server; 10.3.2.131/24
Devices; 10.1.1.1/24

I’m accessing it by IP, I would use a domain if bypassing sso was possible tho.

They aren’t on the same subnet, mais there is intervlan routing so it shoudn’t be a problem, it’s worked before. Especially since I can connect of the web ui on plex (10.3.2.131) and on a page served the the plex server I’m being told to install plex, this is strange.

I do believe there is something about the Plex SSO, but I haven’t find a way to get rid of it.

You are crossing subnet boundaries.

10.3.2.x / 24 is the first
10.1.1.x / 24 is the second

Forget the VLAN routing at this point. That’s switching. (Layer 2)
You first must address the TCP/IP layer (Layer 3)

When claiming a server you must:

  1. Be on the same subnet as it when the server is unclaimed to be considered “Local”.
  2. Anything else is considered “Remote”. PMS protects against being claimed from “Remote” clients. (imagine if this were in a data center and it got signed out. You wouldn’t want it claimable by anyone)
  3. The alternative - SSH tunnel into the server machine (across the subnet)
ssh -L 8888:127.0.0.1:32400  ip.addr.of.host

sign in and let the ssh session sit there as the conduit

Open a fresh , incognito window to http://127.0.0.1:8888/web
