How to Fix “An Unknown Error Has Occurred” in Helldivers 2

When users try to play Helldivers 2, they may encounter an error message stating “An unknown error has occurred.” This error typically indicates issues with the game’s servers, preventing users from accessing or playing the game. In most cases, the error occurs because the servers have reached full capacity and cannot accommodate additional players.

This often occurs during peak times or after major updates when player traffic is especially high. Although the error is primarily related to server congestion, users may also experience it due to network issues or temporary server maintenance.

In this article, we will discuss different solutions to resolve this issue.

1. Restart the Game

A temporary bug might be causing the issue, which can usually be resolved by restarting the game. Restarting refreshes the game environment by reloading assets and clearing any cached data that might be corrupted.

2. Wait for Server Stability

Server downtime can cause problems when loading the game, often resulting from scheduled maintenance, technical issues, or high traffic. You can check the server status on platforms like Downdetector to see if the servers are experiencing widespread outages.

Additionally, the official game website or social media channels may provide updates or estimated times for resolution. If the servers are down, waiting is the best option until the issue is resolved.

3. Check for Background Apps

Background applications can consume significant system resources, leading to performance issues. Closing unnecessary background applications frees up these resources.

1. Press CTRL + SHIFT + ESC simultaneously to open Task Manager.
2. In Task Manager, locate and click on any application you don’t need.
3. Click the End Task button at the bottom-right corner of Task Manager.
   

4. Verify Game Files

Corrupted game files can occur due to incomplete downloads, software conflicts, or hardware issues. Verifying the integrity of game files ensures that all files are correctly installed and up to date.

1. Open Steam and click on the Library tab to see your list of games.
2. Find Helldivers 2 in your game list, right-click on it, and select Properties.
