File Sync Crashing Using Nexcloud On Windows

Using /e/OS Troubleshooting
1

Hi There,

I’m running Nextcloud Files version 3.16.1 and I’m having some issues with the last batch of files for some reason. I can’t tell if this is an issue on the server side or an issue with the Nextcloud client itself. Or, conversely, an issue with Windows. I also have an AppleM1 MacBook air that has no issues syncing files.

When the Nextcloud client starts with my computer, it scans local folders for changes, then begins syncing. I only have about 55 GB left for it to sync, however, it seems to freeze or lock up. If I try pinning the Nextcloud status icon to my taskbar, it locks up Windows Explorer and suddenly I can’t access anything on the taskbar. When I try to click any of my programs (or use keyboard shortcuts to open them) it get stuck and won’t open. The status in Nextcloud sync client says something to the effect of “101 Files of 5200 Files synced.” The time to upload goes from 2 hours to several days and keeps climbing before setting to 0 (see screenshot below:)

I currently have mine configured to “use online files only.”

Here are my Windows computer specs for reference:

Edition Windows 11 Home
Version 24H2
Installed on ‎3/‎16/‎2025
OS build 26100.3476
Experience Windows Feature Experience Pack 1000.26100.54.0
Processor 13th Gen Intel(R) Core™ i5-1335U 1.30 GHz
Installed RAM 8.00 GB (7.69 GB usable)
System type 64-bit operating system, x64-based processor

Here’s a summary of the steps I’ve tried so far (to the best of my recollection)

  • Uninstalled/reinstalled Nextcloud client
  • Repaired Nextcloud client using Control Panel
  • Enabled upload/download limiting (just to see if that made any difference)
  • Re-installed Windows (keeping local files and profile as to no lose any data)
  • Tried uploading both using a VPN and without to see if there might be a throttling issue with my ISP

Looking around online, I’ve seen lots of these kinds of issues with self hosting instances of Nextcloud Files with older builds of the program.

Has anyone else run into issues with this since files storage has been re-implemented?

Thanks in advance,
-Mel

I forgot to mention:

  • This afternoon my computer bluescreened. It appears to be working after the restart
  • If I close Nextcloud the computer performs normally, so I assume that’s the culprit.
  • I’m running SentinelOne for antivirus, however, I haven’t reinstalled it since resetting Windows so I don’t think that could be causing the issue.

did you enable client syncing? murena put that behind a checkbox after the outage

Yup, that has been checked!

I thought the issue might have been caused by adware on my PC, but after running multiple cleanup scans using several tools, the issue has returned.

Just a thought … might your cloud storage be becoming full ?

  • I think there was a change in eDrive which might prevent users accidentally over-topping their limit.

My storage appears ok at the moment, if I need more room I can always pay for more:

I left my PC running overnight in hopes that might give it time to update. It got stuck early on then never progressed. I’m tempted to just try uploading what hasn’t copied to the web interface and call it a day.

I changed my settings from “sync virtual files” to download only those folders that needed updating. This allowed the files to sync successfully. When done, I removed the folders I no longer needed from local sync.

Hi, perhaps I have the same problem. When I start sync, the upload speed decreases until it stops completely.

Here is a recording:

changed my settings from “sync virtual files” to download only those folders that needed updating.

Is this setting on desktop app or on web interface?
