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?
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?
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”.
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.
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.
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.
