The most common cause is an unstable internet connection, especially when using a VPN that interferes with Ubisoft’s server communication or changes DNS routing. Other factors include firewall restrictions, corrupted local save files that the client fails to parse, and temporary server-side issues on Ubisoft’s end. You can verify if Ubisoft services are down by checking their official status page or forums. In some scenarios, Ubisoft Connect mismanages save file paths after game migration, reinstallations, or custom directory changes—leading to unsynced data. The client may also fail to prompt users during cloud vs. local save conflicts, risking unintentional data overwrites. The fixes listed below address permissions errors (such as missing write access to the save directory), firewall blocks, and OS-level issues like antivirus interference or restricted folder access. These solutions are especially useful when trying to fix Ubisoft cloud sync issues.
1. Toggle Offline/Online Mode
This solution enables Ubisoft Connect to re-establish its connection with cloud servers by forcing a fresh login state. This often resolves temporary sync glitches caused by an improper connection between the client and Ubisoft’s servers. To do this, navigate to C:\Program Files (x86)\Ubisoft\Ubisoft Game Launcher\savegames[YourUserID] or C:\Users[YourName]\Saved Games\Ubisoft Game Launcher copy the folder corresponding to your game, and paste it to a safe location like your Desktop or an external drive. ⚠️ Note: This method involves editing a configuration file. Create a backup of the file before making any changes to avoid errors. Now launch Ubisoft Connect. It should start in offline mode. Afterward, you can disable offline mode from the client’s own settings to re-establish a clean connection with the cloud servers. This forces a reset of the sync mechanism and may help fix persistent sync errors.
2. Set Ubisoft Connect to Always Run as Admin
Running Ubisoft Connect with administrator privileges ensures the application has the necessary permissions to modify system folders where save files are stored. Many sync issues occur when the client lacks write access to the savegame directory, especially on restricted user accounts or systems with aggressive antivirus or UAC settings. The UPlayWebCore.exe component is responsible for handling web-based interactions within Ubisoft Connect, including authentication and syncing services. Granting it administrator access helps prevent silent permission failures during background sync tasks.
3. Manual Save Folder Cleanup
Renaming the save folder prompts Ubisoft Connect to re-fetch clean cloud copies, bypassing potentially corrupted local files. This method can restore cloud integrity while preserving your most recent gameplay—but only if a valid cloud version exists.
4. Verify Game Files
File verification compares your local game installation against the official Ubisoft servers, replacing any corrupted or altered files. While cloud sync operates independently, verifying your files ensures the game runs properly and helps prevent save loading issues caused by faulty installations.
5. Cloud Sync Reset
This method resets Ubisoft’s cloud sync system by disabling it temporarily, removing potentially corrupted local saves, and generating a clean new save. Afterward, Ubisoft Connect will prompt you to select between local and cloud saves—allowing you to safely overwrite the cloud with the new version. If none of the above methods resolve the issue, your best option is to contact Ubisoft Support directly for further assistance. They can check for account-specific or server-side problems that may not be fixable on your end.
