Cannot reclaim server after moving to DMZ subnet

Plex Media Server

Server Version#: 1.43.0.10492
Player Version#:
<If providing server logs please do NOT turn on verbose logging, only debug logging should be enabled>

I’m trying to move my server to a DMZ on my router for security purposes. When I move the connection over to the new IP, there must be a mismatch in the token it’s looking for since I cannot access it. I followed the instructions from this article to remove the registry entries, and when I go to “Open Server” from the system tray I get an infinitely looping webpage that says “Getting ready…”

I have also tried unclaiming the server in the settings before swapping the patch cable around and the same thing happens.

My metadata files are backed up and I could reinstall from scratch but I’d like to avoid that if possible. Thanks

EDIT: I’m accessing the server over Remote Desktop from a different subnet. I don’t see how this would cause the issue since I’m still accessing it on localhost but figured I’d mention it.

If you are accessing it via localhost (via RDP) IP subnetting shouldnt matter unless you are not following RFCs. Can you post a copy of your server logs?

3

Doing so will not improve the security of your server. Quite the opposite.
Plus, you may get trouble accessing the server from inside your local network.

Not recommended.

It doesn’t make the server itself any more or less secure but it does protect the rest of the network in case the server is compromised.

I did some reading and I think clearing my browser cookies on the localhost might help, if it’s retaining token information there causing the mismatch. If that fails I’ll post the server logs. Is there a particular kind of error you’re looking for? I ask because my log files are….. messy

Thats why we ask for the log zip. Those of us who know how to process them dont care how messy you think they are. There are about 10 different things I have a script check for before I manually review the logs.

Thanks for sending the logs over via PM. I am not seeing anything major. I am seeing:
Mar 16, 2026 14:53:32.689 [4792] DEBUG - Request: [10.3.7.7:54413 (Subnet)] GET /diagnostics/logs (13 live) #211 GZIP Signed-in Token How are you getting the server logs if the server wont load?

I would suggest using an incognito tab and see what that does. I will also say you may need to check browser permissions as they may need that to connect to devices on your local network (simi-recent update to most browsers)

Those are the logs after resetting it on the original subnet. Which I’m just now wondering, do the logs clear each time the server is started up?

Ah ok, that information would have been useful :smiley: check your DNS, DHCP, and that it can connect to the plex servers from your DMZ.

EDIT: The logs dont reset, but if Im not aware of what happened I wont look for more than the obvious results.

EDIT2: From the logs
Mar 16, 2026 14:51:10.003 [17576] WARN - [HttpClient/HCl#3] HTTP error requesting POST https://plex.tv/api/v2/pins?strong=true (6, Couldn't resolve host name) (Could not resolve host: plex.tv)
looks like DNS issues

You are 100% correct, it was a typo in my firewall rule for DNS. I mixed up the second and third numbers in the IP for the server so it wasn’t working even with 8.8.8.8 and 1.1.1.1 set manually. What’s weird is web pages were loading from the DMZ, but I guess the browser must cache DNS information for pages it’s been to before.

Thanks so much for your help, I’m glad it was something simple and me being dumb instead of a huge issue.
