Lightroom Classic 15.6 sync hangs.

Lightroom Classic 15.6 Syncing is hanging for me. I started by deleting all my existing cloud data so that everything would be fresh today and then tried to sync a bunch of collections. Some already have smart previews, some don't. There are about 2500 images. Most of the images have synced but now I am down to the last 150, syncing seems to stop or hang. It now does anything between 2 and 4 each time I start lightroom, but no more. I have to close and restart for sync to continue. Is there a fix for this? Is it a known issue?

Hi ​@nickb37966070 

 

Sorry to hear you're running into this sync issue, and thanks for explaining what you've already tried. Could you share a few more details so we can narrow this down?

  • Which operating system are you using?

  • When the sync stalls, what does the Cloud icon in Lightroom Classic show?

  • Go to Preferences > Lightroom Sync. Do the remaining images appear there as actively syncing, or do they show any errors?

  • Do you see an All Sync Errors collection in the Catalog panel? If so, please check whether any of the remaining images appear there.

  • If possible, please share a screenshot of the Lightroom Sync preferences when the sync is stuck.

You can also hold Alt (Windows) / Option (macOS) while in the Lightroom Sync preferences to reveal View Sync Status on Web. Please check whether the remaining images show any sync errors there.
