Fix: Failed to Synchronize Achievements Error on Uplay

Do you encounter a “Failed to Synchronize Achievements” error on Uplay?

Besides being the official game launcher of Ubisoft titles, Uplay is also responsible for storing your in-game progress and achievements. This means you don’t have to worry about losing your progress in case you need to uninstall your games. 

Unfortunately, there have been reports from users who struggle to load their in-game progress due to a “Failed to Synchronize Achievements” error. 

Most of the time, this issue on Uplay is caused by third-party antivirus or Windows Firewall restricting network access to the app. However, it can also be due to corrupted game files or invalid host file entries related to Uplay. 

The “Failed to Synchronize Achievement” error on Uplay is also not isolated to a single game and can occur on any Ubisoft title. 

To help out, we’ve decided to make a guide for fixing the “Failed to Synchronize Achievements” error on Uplay. 

Let’s get right into it!

1. Restart Your PC. 

Whenever you encounter issues with Uplay or any application, the first thing you should do is restart your computer. This should reload your system resources and eliminate errors that may have occurred during use. 

Here’s what you need to do: 

  1. On your keyboard, press the Windows key to open the Start Menu
  2. After that, access the Power Options tab. 
  3. Finally, choose Restart to reboot your system.

Go back to Uplay afterward and check if the error message still occurs. 

2. Reinitialize Online Status. 

There’s a known bug or glitch that occurs between Uplay’s servers and the PC client that causes the “Failed to Synchronize Achievements” error. Fortunately, the issue can be resolved by simply going offline, then online again. 

See the steps below to guide you through the process:

Once done, try loading your game and see if the synchronize error still occurs. 

3. Close Uplay Using Task Manager. 

Restarting the Uplay client might not be enough to address this issue. As it turns out, the launcher continues to run other processes in the background even if the client is closed, which essentially doesn’t restart the entire application. 

To fix the issue, we suggest closing Uplay and its related processes using the Task Manager to ensure it’s fully closed. 

  1. Launch the Task Manager by pressing the CTRL + SHIFT + ESC keys on your keyboard. 
  2. After that, go to the Processes tab.
  3. Find any Uplay-related tasks and close them.

To fix this, follow the guide below to allow Uplay on Windows Defender Firewall:

6. Check Your Network Connection. 

A slow or unstable internet connection could also be the reason you encounter the “Failed to Synchronize Achievements” error on Uplay. To confirm this, perform a test using to measure your network’s upload and download bandwidth.

If the test indicates a problem with your connection, we recommend restarting your modem or router to refresh the link between your device and your ISP’s servers.

Re-run the test on your network to confirm if the restart worked. If not, get in touch with your ISP and ask them to fix their service.
