Solution to Light synch failed #99557

https://thebrain.zendesk.com/agent/tickets/99557

Hello Antonio,

Thank you for sending the log file so promptly, that helped clarify what’s happening.

We can see a specific error during the attachment download. The sync is failing because Windows is denying access to this file on your system:

cytoa24471-sup-0002-tables2.xls

located here:

C:\Users\acosma\Brains\U01\B02\d3cc8a66-65f0-4ee7-b90f-2f3ff2e9fe1e\

Please try the following:

1. Open File Explorer and navigate to the folder above
2. Right-click the file cytoa24471-sup-0002-tables2.xls
3. Choose Properties
4. In the General tab, check the Attributes section
5. If Read-only is checked, uncheck it and click Apply
6. Then reopen TheBrain and try syncing again

If the file is not marked read-only, the most likely cause is another process interfering with access to the Brains folder, such as Windows Defender, backup software, cloud sync tools, or other third-party utilities that may be locking the file while TheBrain is trying to download it.

Light Sync itself is behaving as designed here. The attachment download failure is what triggers the error and causes Light Sync to re-enable automatically.

Please let us know what you find after checking the file properties, and whether the issue persists.

Best regards,

John
