• Plex Media Server: 1.43.0.10467-2b1ba6e69
• OS: Ubuntu 24.04 (native install, not Docker)
• Plex Pass: Lifetime
• Clients: iOS + Android (same behavior)
• Downloads started from mobile apps (not web)
• Client is on same LAN as server
Server log (every attempt): 404 POST /downloadQueue/5/add
Already verified:
Downloads temp directory exists, writable, plenty of space
Library allows downloads
Simple H.264 media, no subtitles
Preferences.xml valid
Full stop → remove → reinstall of Plex Media Server (data preserved)
Streaming works fine. Only downloads fail.
Looks like the server is explicitly rejecting the download queue request.
Is this a known regression or something else to check?
Is this field populated in your server settings?
If it is, remember that it needs to have the same access permissions as the Plex data folder.
If it is not, verify that it is actually completely empty (and doesn’t have any spaces, tabs or other whitespace characters in it).
Are the download attempts performed with a client that is signed into your own Plex user account?
The Downloads Temp Directory is populated, exists, and has the same permissions as the Plex data folder. I’ve confirmed it’s completely clean with no extra spaces or hidden characters.
All download attempts are performed from clients signed into the same Plex account that owns the server.
Happy to provide any further details if needed, and thanks for your help!
