Warzone Stuck on Checking for Updates? Fixes

Card No. 06·43951 · Updated · Standard formula, shown below

If Call of Duty: Warzone is stuck on the “Checking for updates� screen, the game cannot connect to the update server or is waiting on a corrupted file, and the fix usually involves restarting the launcher, clearing the cache, or repairing the game files. Below are the specific steps for Battle.net, Steam, and console, plus the reasons this happens and how to prevent it.

Why Warzone Gets Stuck on “Checking for Updates�

The “Checking for updates� step is the game client contacting Activision’s update servers to see if a new patch is available and to verify the local files. When it hangs, one of these is usually wrong:

  • Server outage or high load: On major patch days, millions of players hit the servers at once, and the client can time out while waiting for a response.
  • Corrupted game files: A partial download or a failed update leaves a file that the client keeps trying to verify, and it never finishes.
  • Network or firewall interference: A VPN, proxy, or overly strict firewall can block the connection to the update servers even if the rest of your internet works.
  • Launcher cache problems: Battle.net and Steam both store temporary data that can become stale and cause the update check to loop.
  • Background processes: Another instance of the game or launcher running in the background can lock the update files.

Quick Fixes That Usually Work

Try these in order, because they solve the majority of cases without any downloads:

  1. Fully restart the launcher and the game. Close Battle.net or Steam completely (check the system tray for Battle.net), then reopen it and launch Warzone again.
  2. Restart your PC or console. A clean reboot clears stuck processes and resets network connections.
  3. Pause and resume the update. If you see a progress bar that’s frozen, pause it for 10 seconds, then resume. This often kick-starts the download.
  4. Check server status. Visit the official Activision Support page or their social media to see if there’s a known outage. If there is, wait it out.
  5. Disable VPN and proxy. Turn off any VPN or proxy software, then retry. If it works, your VPN was the problem.

Clear the Launcher Cache

If the quick fixes don’t work, the launcher’s cache is likely corrupted. Here’s how to clear it on each platform:

  • Battle.net (Windows): Close Battle.net. Press Windows + R, type %ProgramData% and press Enter. Find the Battle.net folder and delete the Cache folder inside it. Also open %AppData% and delete the Battle.net folder there (this resets your login, so you’ll need to sign in again).
  • Steam: Close Steam. Navigate to your Steam installation folder (usually C:\Program Files (x86)\Steam). Delete the appcache folder. Restart Steam.
  • Xbox: Press the Xbox button, go to Profile & system > Settings > System > Storage devices. Select Clear local saved games (this does not delete your cloud saves). Then restart the console.
  • PlayStation: Turn off the console completely. Unplug it for 30 seconds, then plug it back in and turn it on. This clears the system cache.

Repair or Scan Game Files

If the cache clear doesn’t help, the game files themselves are probably damaged. Each launcher has a built-in repair tool:

  • Battle.net: In your game library, click the Warzone icon, then click the gear icon (Options) > Scan and Repair. A window will appear with a “Begin Scan� button. Let it run; it will re-download any missing or corrupted files.
  • Steam: Right-click Call of Duty: Warzone in your library, select Properties > Local Files > Verify integrity of game files. Steam will check and re-download what’s needed.
  • Console: On Xbox, highlight the game tile, press the Menu button, and select Manage game and add-ons. Then select “Uninstall� (you won’t lose your progress) and reinstall. On PlayStation, go to Settings > Storage > Games and Apps, find Warzone, and delete it, then reinstall from your library.

Network and Firewall Adjustments

Sometimes the issue is that your router or firewall is blocking the specific ports Warzone uses. You can try these steps:

  • Flush DNS: Open Command Prompt as administrator and run ipconfig /flushdns. Then restart the launcher.
  • Change DNS server: Switch your DNS to a public one like Google (8.8.8.8 and 8.8.4.4) or Cloudflare (1.1.1.1). This can bypass a misconfigured local DNS.
  • Add exceptions in Windows Defender: Go to Windows Security > Firewall & network protection > Allow an app through firewall. Make sure both Call of Duty and the launcher (Battle.net or Steam) are checked for Private and Public networks.
  • Power cycle your router: Unplug the router for 30 seconds, plug it back in, and wait for it to fully boot before retrying.

What Not to Do

Some common advice can make things worse. Avoid these:

  • Don’t delete the entire game folder manually. That can leave registry entries that cause more problems. Use the launcher’s uninstall option if you need to reinstall.
  • Don’t disable your firewall entirely. That exposes your PC to threats. Add exceptions instead.
  • Don’t use “run as administrator� as a permanent fix. It can mask permission issues but may cause other problems. Only try it once as a test.

Frequently Asked Questions

Why does Warzone get stuck on “Checking for updates� after every patch?

It’s usually because the update servers are overloaded right after a patch releases. The client times out and doesn’t retry properly. Waiting 30–60 minutes and then restarting the launcher usually fixes it. If it happens every time, your local files might be corrupted, so run a scan/repair.

Will I lose my progress if I reinstall Warzone?

No. Your progress, loadouts, and purchases are tied to your Activision account, not to local files. Reinstalling only deletes the game data on your device. You’ll need to re-download the game, which can be large (over 100 GB on some platforms).

Does clearing the Battle.net cache delete my games?

No. The cache folder only contains temporary data like login tokens and UI settings. Deleting it will not remove your installed games, but you will have to log in again. Your game settings (like graphics) are stored elsewhere and won’t be affected.

Can a slow internet connection cause this problem?

Yes, but not in the way you might think. A slow connection can cause the update check to time out, especially if the server response is delayed. However, even a fast connection can get stuck if the server is down. If your connection is slow, try pausing other downloads and using a wired Ethernet connection.

Is there a way to skip the update check and play offline?

No. Warzone is an online-only game, and the update check verifies that your game version matches the server’s. You cannot bypass it. If the update won’t complete, the only option is to fix the underlying issue (server, files, or network).
