Error while syncing (Report ID: 716863947)

edited March 15, 2025
After it has worked like a charm ever since I started using Zotero, since today, I get an error when syncing my library:
"A file sync error occurred. Please try syncing again."
Sometimes it also syncs forever resp. until I close Zotero. It seems like the syncing process gets stuck somewhere.

I have automatic sync disabled as it slows everything down too much. So, I get the error, whenever I hit the sync button. Interestingly, I only get this error message on one of my devices. The others seem to sync fine.

I have restarted Zotero and rebooted my PC but I still get the error message.

In case it is relevant: When I hit the sync button and i hover above the sync icon, the tooltip keeps saying "Syncing files in My Library (3 remaining)". However, I can see that my latest changes (adding annotations in PDFs and deleting saved searches) did get synced. Or at least, I think, those were my last changes...

Any pointers on how to resolve this error are much appreciated!
  • This should be fixed now in Zotero 7.0.15. (It could happen starting in 7.0.14 if a download took longer than 30 seconds.)
  • Just updated to 7.0.15 and like you said the issue was gone. Thank you for this support and the awesome work in general!
