How to fix error 0x887a0005L?

Here are five fixes you can try out. 

Restart your PC

Restarting your PC can fix several seemingly random issues you might encounter with your games or programs. A simple reboot will reset your system resources and allow your PC to allocate resources and network bandwidth where needed, avoiding such problems. 


Restart your game

One of the easiest ways to fix the problem is to restart the game. Restarting games and programs often resolves temporary bugs that can cause crashes or connectivity issues. Once the game is stopped completely (you can verify this using the Task Manager), relaunch it using the Steam or Battle Net launcher, and it should work just fine.

Step 1: Open the Battle Net desktop app and click the cogwheel icon next to the play button. 

Step 2: Click Scan and Repair.

On Steam

If you’re using Steam, follow these steps to verify game file integrity. 

Step 1: Head to your Steam Library, right-click on Call of Duty: Modern Warfare 2.0 and select Properties.

While this should help resolve the error, if it doesn’t, click Uninstall device and restart your PC to force Windows to install the required drivers. You can then update them later. Alternatively, you can also remove your GPU and reinsert it. 


Reinstall

Your best bet is reinstalling the game from scratch if nothing else works. This will overwrite any damaged or corrupt files or configurations that might keep you from connecting to online matchmaking.
