Dropbox Not Syncing or Working on Windows 11/10

Quick fixes overview:

1. Check internet connection
2. Verify account password
3. Check storage space
4. Review camera uploads settings
5. Don't limit bandwidth
6. Validate filenames
7. Disable VPN and proxy
8. Check selective sync
9. Clear cache
10. Disable firewall software

Read on for detailed, step-by-step guidance on each.

1. Check Your Internet Connection

The top reason Dropbox fails to sync is a faulty internet connection. Dropbox needs reliable web access to upload and download files.

Test it by loading a website in your browser or opening Command Prompt and running:

ping 8.8.8.8 -t

If responses fail or lag, switch to a stable network.

2. Verify Account Password

A recent password change halts syncing until you re-authenticate. Dropbox prompts for new credentials, but if not, go to Account in Preferences and select Sign out.

Then log back in with your email and updated password.

3. Check Storage Space

Free accounts get 5GB; paid plans offer more. Running out of space blocks new uploads – e.g., a 150MB file won't sync if only 100MB remains. Monitor usage in your account dashboard and free up space as needed.

4. Review Camera Uploads Settings

Auto-uploads for photos/videos mimic OneDrive. If set to photos only, videos won't appear. Fix it:

• Open Dropbox Preferences.
• Go to Backups.
• In Camera uploads, select Photos and videos.
• Click OK.

Files will now sync automatically.

5. Don't Limit Bandwidth

Throttling prevents data overuse but slows large files if misconfigured.

• Open Preferences > Bandwidth.
• Set Upload and Download to Don't limit.
• Click OK and restart Dropbox.

6. Validate Filenames

Invalid characters prevent uploads. Examples to avoid: *my picture (asterisk invalid), colon (:), double quote ("), vertical bar (|), question mark (?), trailing period (.).

Rename problematic files and retry syncing.

7. Disable VPN and Proxy

VPN/proxy interference mimics connectivity issues. Disable VPN temporarily. For proxy:

• Preferences > Proxies.
• Select Auto-detect or No proxy.

8. Check Selective Sync

This lets you choose folders to sync. Misconfiguration skips items.

• Preferences > Sync.
• Check desired folders.
• Click Update.

9. Clear Cache

Corrupted cache causes glitches:

• Press Win + R, enter %HOMEPATH%\Dropbox\.Dropbox.cache.
• Delete contents (not folder).
• Empty Recycle Bin and restart Dropbox.

10. Disable Firewall Software

Third-party firewalls block Dropbox traffic. Temporarily disable via its settings or add an exception for Dropbox.exe.

How to Sync Dropbox in Windows 11

Sync works out-of-the-box. For Selective Sync issues: Preferences > Sync > Selective Sync to include/exclude folders.
