How to Fix Destiny 2 Error Code CAT (PC, PlayStation, Xbox)

Destiny 2 error code CAT stops you from logging in and usually shows up right when a new update or hotfix goes live. It almost always comes down to your game client falling out of sync with Bungie’s servers, whether that is a pending download you have not installed yet or a maintenance window that has not finished. CAT has nothing to do with your save data or account, and most players clear it within a few minutes once they know what to check. This fix walks through why the error appears and how to resolve it on PC, Xbox, and PlayStation.

What Causes Error Code CAT

Error code CAT is tied to game updates and server states, not corrupted files or account issues. These are the main triggers.

• Your installed game version is older than the live server version
• Bungie has taken servers offline to deploy a new update or hotfix
• A new season or expansion just launched and your platform has not pulled the update yet
• The download finished on Bungie’s end but has not synced to your platform’s store

Fix 1: Restart Your Game Client to Force the Update Check

Most CAT errors clear once your launcher detects and installs the pending update.

Steam

1. Close the Steam client completely, including from the system tray.
2. Reopen Steam and go to your Library.
3. Check if Destiny 2 shows a pending update and let it install.
4. If no update appears, right-click Destiny 2 and select Properties.
5. Open Installed Files and click Verify integrity of game files.

Epic Games Store

1. Quit the Epic Games launcher from the system tray.
2. Relaunch the app and open your Library.
3. Let the automatic update download complete.
4. If it does not start, click the three dots next to Destiny 2.
5. Toggle Auto Update off, then back on to force a check.

Xbox

1. Open My Games and Apps from the Home menu.
2. Select Manage, then Updates.
3. Choose Destiny 2 and let the update install.
4. If no update shows, fully power cycle the console, then reopen My Games and Apps and check Updates again.

If No Update Appears on Xbox

1. Power off the console completely.
2. Unplug the power cable and wait 5 minutes.
3. Plug the cable back in and restart the console.
4. Check for the update again.

PlayStation 5

1. Open the Destiny 2 tile under Games.
2. Press the options button on your controller.
3. Select Check for Update and let it install.

PlayStation 4

1. Press up on the D-pad to open Notifications.
2. Select Downloads.
3. Choose the Destiny Update File and let it install.

If No Update Appears on PlayStation

1. Power off the console completely.
2. Unplug the power cable and wait 5 minutes.
3. Plug the cable back in and restart the console.
4. Check for the update again.

Fix 2: Wait Out an Active Maintenance Window

If your game is already fully updated and CAT still appears, Bungie is likely running a maintenance window before or during a patch rollout.

1. Open Bungie Help on X or Bluesky.
2. Look for a recent post confirming scheduled maintenance or an update rollout.
3. Note the expected end time if Bungie has posted one.
4. Avoid repeated login attempts until Bungie confirms servers are back online.
5. Retry login once Bungie posts that maintenance has ended.

Logging in during this window returns error code CAT even on a fully patched client, since the servers themselves are not accepting connections yet. Expansion launches and major season updates carry longer maintenance windows than routine hotfixes, so expect a longer wait during those periods.

Fix 3: Enable Automatic Updates to Prevent Future CAT Errors

Once your game is running normally again, turning on automatic updates keeps your client in sync with Bungie’s servers so you are less likely to hit CAT after the next patch.

Steam

1. Right-click Destiny 2 in your Library.
2. Open Properties.
3. Go to the Updates tab.
4. Set the game to update automatically whenever it is running.

Xbox

1. Open Settings, then Power and Startup.
2. Select Power Mode and Startup.
3. Enable Keep my console, games & apps up to date.
4. On Xbox Series X/S, go to Systems > Updates instead and enable the same toggle.

PlayStation

1. On PS5, open Settings, then System.
2. Select System Software.
3. Enable Download Update Files Automatically.
4. On PS4, go to Settings > System > Automatic Downloads.
5. Turn on Application Update Files.
