Android downloads fail with 404 because the Emby sync file is missing

[OUARZA 5]

Hello,

I’m having recurring problems downloading TV episodes for offline viewing. Some items stay on “Ready to transfer” or fail. This happens on two Android phones.

Setup

• Emby Server 4.10.0.40 on a Synology DS720+
• Emby for Android 3.5.55 on Android 17

In the latest server log, repeated requests to /emby/Sync/JobItems/277/File fail with DirectoryNotFoundException. Emby says the temporary file under /var/packages/EmbyServer/var/sync/91/277/ does not exist, and returns HTTP 404.

Some FFmpeg and ffprobe operations in the log exit with code 0, but the Android download still fails when it requests the sync file.

The log also contained an earlier Permission denied error when Emby tried to copy a converted file into my media share. I have since granted the internal emby user read/write access to the Download shared folder, but the Android download problem persists.

Could this missing temporary sync file be a known issue with Emby Server or the Android app? What logs would help diagnose it further? I purchased the Android app and would appreciate your help.

Thank you.

Hi there, please attach the Emby server log from when the problem occurred:

AFAIK that is not feasible (and again, don't think it ever will be), even with the current TVDB-only implementation for alternate episode orders, you need to (re)name/(re)structure the files in the underlying OS accordingly and refresh metadata, you can't just switch display/presentation as you see fit with single set of data. 

Hi, no, the likely answer is that it was deleted from the server before the app had a chance to download it.

Thanks. I’ve attached the Emby server log from the failed download. The log shows repeated 404 errors for /emby/Sync/JobItems/277/File because the temporary file under /var/packages/EmbyServer/var/sync/91/277/ is missing. Please let me know if you need any other logs or details.

Hi Luke,

I’ve found some notifications from the latest download attempt that may help. I’m attaching the screenshots and a fresh Emby server log covering this attempt.

At 16:59, Emby notified me that Episode 2 of L’amour est dans le pré had downloaded successfully. At 17:05, I got a “Download completed” notification for Episode 3, but another notification at the same time showed Episode 3 still downloading at 99% (3103 MB/3112 MB). Later, at 17:29, Emby showed “Removing Downloads” for Episode 3.

Despite the completion notifications, I can’t find the episodes in the app to watch offline. I have “Download only unwatched videos” enabled. Could that setting explain why Episode 3 was removed, or do the notifications suggest that the same episode was queued twice?

This is still happening with Emby Server 4.10.0.40 on my Synology DS720+ and Emby for Android 3.5.55 on Android 17. I’ve also attached the hardware detection report.

Thanks for your help.

Hi @Luke,

I wanted to follow up with a new test and a couple of screenshots.

I found that the users group did not have write permission on the destination folders. I corrected the permissions, and transfers are now progressing. My Emby Server on the Synology DS720+ is now updated to 4.10.1.0; the Android app is still 3.5.55.

There still seems to be an inconsistency in the download notifications. At 20:30, Emby reported “Download completed” for La Revanche des Cerises Trotinettes. At the same time, another Emby notification still showed “Downloading 3 items”, listing that title along with other items, while Episode 4 was at 49%.

Could this indicate that the same item is being queued or processed more than once, or might the notification simply be stale? I’ve attached the screenshots. Please let me know if a fresh server log from this test would help.

Thanks!

Given all of the failures you  had, it’s hard to say. We might be able to determine that with a brand new download.
