6. Try the UWP version

UWP upgrade

You can download the UWP version of Dropbox from the Windows Store for free.

If you’re having problems with the regular version of Dropbox, go ahead and try the official UWP client, that’s better optimized for the Windows 10 environment.


7. Run the Troubleshooter app

  1. Go to Settings.
  2. Head over to Updates & Security and select Troubleshoot. 
  3. Click on Windows Store Apps.
  4. Go to Run the Troubleshooter. 
  5. Follow further on-screen instructions and let the process finish.
  6. Restart your PC.

8. Add Dropbox to the Firewall exception list

Firewall exception list

  1. Go to Search and type firewall.
  2. Open Windows Defender Firewall. 
  3. Go to Allow an app or feature through Windows Defender Firewall. 
  4. Select Dropbox.
  5. Make sure to check both Private and Public.
  6. Save the changes and restart your PC.

If the Firewall is actually blocking Dropbox, you don’t need to disable the Firewall completely. It’s enough to just add Dropbox to the exception list, and your cloud service should function normally.

The same thing goes for your antivirus. So, if you still have problems even after whitelisting Dropbox in the Firewall, make sure to do the same in your third-party antivirus.


That’s about it. We certainly hope at least one of these solutions helped you resolve problems with Dropbox in Windows 10.
