How to Fix “1000 – Backend Error” in Escape from Tarkov

The error “1000 – Backend error” indicates a failure in the Escape from Tarkov back-end services, which prevents the game from connecting to datacenters to function properly. This error often occurs during gameplay or loading into a raid, leading to player disconnection mid-game and blocking access to the game.

This issue is primarily caused by equipping incompatible loot items, such as an M700 rifle with a Razor scope or cultist knives. Additionally, server outages, corrupted cache or game files, or interference from Windows Firewall can also trigger this error.

Now that you know the causes, let’s discuss the solutions.

1. Check Server Status

Server outages or issues with the back-end servers can lead to this error. Checking the server status will help determine if server problems are responsible for this error. You can check the server status on the EFT status page, Down Detector, or via Tarkov Server Status.

2. Restart the Game

Temporary connection issues can lead to this error. Restarting the game can help fix these issues by reconnecting to the servers and clearing all temporary cache data that may be causing the problem.

1. Right-click on the taskbar and select Task Manager.
2. Identify and select processes related to Escape from Tarkov.
3. Right-click on the selected process and choose End Task.
   
4. Restart the game.

3. Clear Cache

Corrupted cache data can interfere with server connections, leading to this error. Clearing the cache will remove corrupted data, ensuring a fresh connection between the game and servers, which can help resolve this error.

1. Search for BSG Launcher and run it as Administrator.
2. Click the arrow next to your username.
3. Select Clear Cache and then reopen the launcher.
   
4. Check for and install any available game updates.

4. Verify Game Files

This issue can arise due to corrupted or missing game files affecting server connectivity. Verifying the game files will scan and replace any corrupted or missing files, which could help resolve the error.

1. Launch the Battlestate Games launcher.
2. Locate and click on the gear icon in the upper-right corner.
3. In the settings menu, select the “Integrity Check” option.
   
4. Restart the launcher and launch the game once the process is complete to see if the issue is resolved.

5. Add Game to Firewall Exemption

Windows Firewall may sometimes block the game’s internet access, causing this error. Adding the game to the Firewall exemption list will stop the firewall from interfering with the game, ensuring smooth communication between the game and servers, which could help resolve the issue.

1. Search for “Firewall & Network Protection” in the search box and open it.
   
2. Select “Allow an app through firewall”.
   
3. Click on Change Settings.
   
4. Click on Add another app.
   
5. In the popup window, click on Browse, navigate to Escape from Tarkov’s installation path, and select EscapeFromTarkov.exe.
6. Select Network Types and check both Private and Public options.
   
7. Click Add to whitelist it in Windows Defender Firewall.

6. Delete Old .ini Files

.ini files store game data related to the in-game store, settings, and system configurations essential for running the game. If this data becomes corrupted or outdated due to game updates, it can cause issues. Deleting old .ini files will remove outdated data and create new files compatible with current game configurations, which can help solve the error.

It is recommended to create a backup of these files before deletion in case they are needed in the future.

1. Press Windows + R, type ‘%localappdata%‘, and press Enter.
   
2. Navigate to the Escape from Tarkov folder and find the settings.ini file.
3. Right-click on it and choose Delete.
   
4. Launch the game to check if the error is fixed.
