Windows: Unable to access server

As of yesterday I’m no longer able to access my Plex server through the web interface. Not even on the machine the server is running on. I get the error, “No content available. Check your network connection and verify that any media servers are online.” However, the Plex app works just fine. Totally baffled. Any idea how to fix?

Here are my logs if they’re helpful.

Without digging into the logs, did you perhaps recently turn on the Windows Firewall? Have you tried disabling it for the sake of troubleshooting? What version of Windows and Plex Media Server are you running?

When you try and access locally, what browser and URL are you using? Localhost? Or trying through app.plex.tv?

I believe the Windows Firewall has been on all along. Turning it off doesn’t help. Windows 11, Plex Media Server Version 4.108.0

Using app.plex.tv, which has always worked till now.

Use Method 2.2 from here: You need to reclaim your server, but don't dare to touch the Windows Registry

There is no need to disable the Windows firewall. It would be in fact quite foolish.
Verify that the network connection in Windows is classified as “private”, not as “public”.

It was suggested for the sake of troubleshooting; I don’t think anyone here suggested it remain off.

Tried Method 2.2. No change.

  1. Verify that you have “automatic time synchronization” activated. Any encrypted communication needs precise time.
  2. if you use a Windows Server edition, see Plex install fix for Windows Server (Claim issue)

  1. Where is that?
  2. Tried it, no change.

I just want to reiterate that I can access the server just fine with the Plex app. It’s exclusively the web app, at app.plex.tv, that suddenly stopped working.

From the machine it’s running on, what happens when you browse to https://localhost:32400/

I get a privacy error:

wot?
Do you have a VPN active?

I do not.

Which kind of web browser are you using?
Any web browser add-ins installed?

What does it say under Advanced?

Try also with just http, not https, and see what happens?
http://localhost:32400/

For what it’s worth I’m having the exact same issue, starting from yesterday. I’ve tried updating to the latest PMS, changing my password and logging out of all devices to trigger a new API token, restarted PMS, restarting the computer, turning off remote access for an hour or two then turning it back on again, changing the public port, removing and reclaiming the server. Nothing seems to work.

Brave. Yes on extensions, but I’ve tried in an incognito/private window, without extensions. Also, my extensions haven’t changed from three days ago.

It works with http.

Please use Chrome or Firefox.
Brave is notoriously sabotaging web apps.

Same problem with Firefox.

Edit: Also, as stated above, “http://localhost:32400/” (not https) works just fine.

In the Plex settings, set “secure connections” to “preferred”, not to “required”.
Then stop and restart the server.
Always keep the server machine on the same network connection. Never flip back and forth between e.g. wired/WiFi, or straight/VPN.

Then investigate a possible interference of your router (or more precisely, your DNS server).
Many of them nowadays apply “DNS rebinding protection”, which will interfere with local access to your server.

Tried that before, no dice.

That doesn’t make much sense, as nothing has changed in the past 3 days.
