Restart game

If you encounter a problem, the first thing you should try is restarting the game. By restarting the game, you can give it a fresh start.

By doing this, there is a chance that minor bugs will be fixed and the game will start working correctly again.

Check your internet connection

The Internet connection plays an important role in the correct launch of the game. If your internet connection is unstable, there is a chance that error code 2901 will appear. Many players have reported that they encountered an issue due to an unstable internet connection. It can happen to you too.

We suggest you check the speed of the internet connection you are connected with. To do this, you need to use an internet speed test. Follow the instructions below to check your internet connection.

Open any browser on your device.
After that, click on the most relevant search result.
Run the internet speed tester and check the download and upload speed of the network you are using.
If the speed is over 50 Mbps, you have a good network connection. But if not, you must fix the router or change the network to make the game run smoothly.

Run the game as administrator

There is a possibility that you may be experiencing error code 2901 because it has not been granted with all the necessary permissions. There is a chance that this will happen, so we suggest that you try giving the game all administrator settings and check if the problem is resolved. To do this, you need to follow the following steps.

First of all, select the game Modern Warfare 2 or Warzone 2.
Now right click on the application.
There you will see the “Run as administrator”option.

Check server failure

Before applying another troubleshooting method, we suggest that you check the status of the game server. If there are problems with the game server, error code 2901 will be detected on the PC. In this case, players will not be able to do anything, because it will come from the backend of the game.

Only developers can solve this problem. Visit the official website of Modern Warfare 2 or Warzone 2 and the official social media account, because if there is any problem with the game server, the company will report it on the website or social media. And if any server crash occurs, you will need to wait for the time to fix it.

Disable Windows Firewall

The firewall can be the cause of the error code 2901. It prevents suspicious activity from getting on the PC and if it has blocked the game, an error code will be displayed on the screen.

We suggest you try restarting the game by disabling the Anti-Virus and checking if it works. You can easily do this by following the steps below.

Open the antivirus that is installed on your PC.
After that, open the settings.
Disable the antivirus in its settings.
That’s all; check if the issue is resolved.

Reinstall the game
