How to Fix Steam Cloud Error on Windows

Have you encountered a “Steam Cloud Error” when running a particular game on the Steam client? This usually happens when Steam’s cloud sync feature is disabled or the Steam server fails to load synced data in time.

Sometimes, however, another Steam client issue causes this error. Whatever the reason why you are getting the Steam Cloud error, here are several solutions you can use to fix it.

Why does the Steam Cloud error occur?

The Steam Cloud error mainly occurs when you play the game on one computer, where your game progress syncs perfectly, but then you launch the Steam client on another computer with Cloud sync disabled. When this happens, your game progress that has already been stored in the cloud may not sync properly.

Steam will likely throw a Steam Cloud error when it finds a progress saved in the cloud that is different from what a game is launched with. This is why it warns that game progress could be lost if started immediately.

Here are some fixes you can try if you are facing the same error while launching the game.


To begin with, you should not launch the game until you have made all the fixes described below. As we mentioned earlier, click Launch anyway in the error window will launch the game, but your game progress will be lost.

1. Make sure cloud sync is enabled in Steam

There “Vapor cloud error” is directly linked to poor synchronization; therefore, make sure that you have not disabled the sync feature of the Steam client. Follow the steps below to confirm that:

  1. Open the Steam client.
  2. In the upper left corner, click the Steam menu and select Settings.
  3. Navigate to the Cloud tab in the left sidebar.
  4. To assure “Enable Steam Cloud synchronization for apps that support it” is checked.
  5. If not, check the box and click OKAY.

Restart Steam once you enable this setting and see if the error persists.

2. Check if the steam is down

Make sure Steam is not experiencing any technical difficulties. If Steam’s servers are having issues, it will prevent the Steam Cloud service from working properly, resulting in the “Steam Cloud Error” message.

Look at him Downdetector official website to see if Steam users have reported any issues. If any relevant issues are reported, look for any official announcement on The Steam Twitter account On the question.

In case of technical problems, you can wait for them to be resolved automatically. However, if the problem is only with you, proceed to the next step.

3. Eliminate any internet problem

Sometimes a slow or no internet connection prevents the Steam client from loading synced progress. Therefore, you should rule out internet-related issues next.

First, check that your PC still has an internet connection. Try opening a website in your browser; If it never loads, try our guide to find out when you can connect to Wi-Fi, but you don’t have an internet connection.

4. Perform a full restart of Steam

To make sure the error is not due to a temporary glitch in the app, you need to close Steam and relaunch it. To ensure that Steam closes completely, you can use the task manager to end all of its processes.

Follow the steps below to end these processes:

  1. To access Task Manager, right click on Windows Begin and select Task Manager.
  2. To end a Steam process, right click on it and select Final task.

After completing all relevant processes, restart Steam.

5. Let Steam properly load all synced data

Giving Steam enough time to properly load synced data can help you fix this error. If you started a game immediately after opening Steam or closing a game, give the client time to catch up before trying again.

6. Eliminate all game-specific issues

The next step is to rule out game-specific issues. To do this, launch a different game than the one in which you are experiencing the error. If you’re having issues with just one game, but other games are working fine, try resynchronizing the game data for that game. Here are the steps you should follow:

  1. Start the Steam client and select the game giving you the error.
  2. Below Cloud StateClick on Desynchronized.
  3. Click on Retry synchronization in the Unable to sync the window.
  4. Wait for the Desynchronized the option changes to Up to date.

Try running the game again and see if you still get the same error. If so, check the integrity of the game file.

7. Check integrity of game files

If none of the fixes solved the problem then it might be caused by corrupted game files, especially those that track game progress. Therefore, you should verify the integrity of game files using the function built-in Steam to eliminate this possibility. Follow these steps to run the check:

  1. Start Steam.
  2. Open your game library.
  3. Right click on the game and select Properties.
  4. Select the Local files tongue.
  5. In the right pane, click Verify integrity of game files…

A successful validation by Steam means no problem with the game files, and the problem is elsewhere. However, if you have any issues, you need to repair the Steam library folder.

8. Repair Steam Library Folder

Repairing the Steam library folder will fix any issues you have had with your game files. Follow the steps below to run the repair:

  1. In the upper left corner, click the Steam menu.
  2. From the menu, select Settings.
  3. Navigate to the Downloads tab in the left sidebar.
  4. In the right pane, click Steam Library Folders.
  5. Next to the folder path, click three horizontal dots and select Repair file.

Follow the on-screen instructions and allow the library folder to be repaired. Test if repairing the folder fixed the error. If not, proceed to the next step.

9. Disable your antivirus or firewall

If your game files are intact, but you’re still experiencing the same issue, your antivirus program or Windows Firewall may be preventing Steam from connecting to the cloud. For this reason, you should disable any third-party antivirus you use and whitelist the Steam client in Windows Defender Firewall.

10. Disable your VPN

Although less likely, running Steam with VPN enabled can also cause cloud sync issues. So if nothing seems to work for you, turn off your VPN and see if that helps.

Fix the Steam Cloud error and save your game progress again

The tips outlined above should help you resolve the Steam Cloud error you’re experiencing. This way, you will no longer lose your game progress when playing on Steam. If you’re still having trouble, contact Steam Support.
