Downloads incredibly slow; requesting same file repeatedly

[slakr007]

I am running Plex Server 1.25.5.5492 as a Docker container under Ubuntu Server 20.04 on an 8-core server with 64 GB of RAM and plenty of bandwidth. I am using Plex app version 7.28.1 on iOS 15.3.

I am trying to download my music library to my phone, and…as has generally been the case with Plex sync/download…the process does not go well. The Plex app appears to be repeatedly requesting the same file until eventually it decides it received it and moves on to the next file. This means that, despite the Plex Dashboard reporting that it is using upwards of 300-400 Mbps of bandwidth, it takes upwards of an hour to download 100 songs.

I have obviously updated both the server and the app. Cleared any temporary data by deleting/reinstalling the app and checking the transcode directory on the server.

I can upload more if necessary, but here are some clips…

Docker command used to create container:

I have the exact same problem.

IPad or iPhone. Latest iOS, latest App, latest server. I have removed and reinstalled the app.

Downloads are set with original quality and original format (instead of maximize compatibility).

Downloads starts and at some point it loops on the same file. Restarting the server does not change anything. Restarting the app sometimes make it works for 5 more song or so and then loops again.

IPad is set with no lock and plugged. I let the UI open in the foreground.

I have tried everything I could and lost 2 days on it before my next travel. Server and apps restarted and reinstalled. Sync was crappy but Downloads is even worst.

Streaming works without problems (unless you have a playlist with Tidal tracks in it, then it never loads on iOS. With the web app you can play it but you cannot see the list, it’s loading forever).

Went to Tidal, found some 400 tracks to sync for my travel. Took few minutes. I am. It sure why I keep Plex and speak about it to friends at this point. Roon solves better my loca library and multi zone, never breaks. Tidal/Spotify/Other is good enough for travels.

Downloads sounds a pretty simple and straightforward feature to code. Do your job.

Experiencing the same issue. Latest beta everywhere, server is on Mac

Same here. Windows server, iOS app. Downloads just cycle over and over. I’ve provided logs in another thread but it’s not getting solved. Very disappointing as a frequent traveler.

Same issue here. Everything’s up today with IOS, Plex app and Readynas214 as my server. A music album will take an hour to download. For some reason Plex is trying to download albums for a second time at random. Somehow it’s deleted the entire album on its own and automatically started downloading (which takes an hour). When I look at how much Mbps are being used in real time on my readynas via the gui it’s like 100Mbps! Mobile App is also very slow to respond now when navigating no matter if I’m connected to my home network or in airplane mode.

Oddly .mp4 files download rates haven’t changed and seem to be okay.

Same issue here.
Windows 11 hosting the Plex server and downloading to iOS devices.
Dashboard shows high speeds (~100Mbps) but the actual download is very slow, plus when anything finishes it downloads it twice.

One workaround I’ve been using is when a download finishes, kill the app and open it again to have it skip that re-download. But, of course, even with that, downloads are still slow.
Using original quality for downloads (no maximize compatibility).
