A Steam Cloud error occurs when there's a mismatch between the game files on your local device and those saved in the Steam Cloud. This safeguard helps prevent unintentional loss of game progress, so resolving the issue before launching your game is crucial.

What Causes the Steam Cloud Error?

When encountering this issue, you may see one of the following alerts:

• Steam Cloud Error
• Steam was unable to Sync your files for (game) with the Steam Cloud
• Unable to Sync

These warnings appear when Steam detects a discrepancy between your local game data and the version stored in the cloud. This commonly happens when playing the same game across multiple devices, but can also occur on a single machine.

The most common cause is making progress in a game on one computer, then launching it on another that isn’t configured to sync with Steam Cloud. Since the saved data differs, Steam triggers a warning. Depending on the situation, you might still be able to play or choose to attempt syncing again.

How to Fix the Steam Cloud Error Message

Try the following solutions to resolve the Steam Cloud error:

1. Attempt to retry synchronization. If the error message includes a Retry Sync option, click it. The problem could be due to a temporary glitch with Steam or your internet connection.

   If the prompt has disappeared, look in your Library for Cloud Status Out of Sync next to the game’s launch button. Click Out of Sync, then choose Retry Sync.

2. Check if Steam is down. Visit the official Steam status page or a third-party site like Steam Status to see if there are ongoing service disruptions.

   If Steam servers are experiencing issues, wait and try again later. Outages can interrupt cloud syncing and lead to errors.

3. Inspect your internet connection. A weak or unstable network connection can interfere with Steam Cloud syncing.

   Test your connection speed and stability. Once any network issues are resolved, return to step one and try syncing again.

4. Enable Steam Cloud sync on your current PC. Often, this error arises when Steam Cloud is enabled on one computer but disabled on another.

   Go to Steam > Settings > Cloud, and make sure Enable Steam Cloud synchronization for apps that support it is checked. Click OK, restart Steam, then try launching the game again.

5. Fully restart Steam. If syncing still fails, completely close Steam and reopen it. Open Task Manager, right-click Steam, and select End Task. Also, end related processes such as Steam (32 bit) and Steam Client WebHelper.

   After ensuring all Steam processes are terminated, relaunch the client and check if syncing works.

6. Verify the game’s file integrity. Corrupted or missing local files can cause sync issues.

   Right-click the game in your Steam library, go to Properties > Local Files > Verify integrity of game files to scan and repair any problems.

7. Repair your Steam library folder. If verifying files doesn’t help, repairing the library folder might.

   Navigate to Steam > Settings > Download > Steam Library Folders. Click the more icon (three dots) and select Repair Folder.

8. Review antivirus and firewall settings. Security software might block Steam from accessing the internet.

   Allow Steam through your firewall or antivirus (e.g., add it as an exception in Windows Defender). Alternatively, temporarily disable these programs to test if they’re causing the issue. If syncing works, re-enable protection and add Steam to the allowed list, or consider switching security software.

To resolve a Steam disk write error, restart Steam, reboot your computer, remove write protection from the drive, and disable the read-only attribute on the Steam folder. If problems persist, run Steam as an administrator or consider relocating the Steam installation to another drive.
