How to Fix ARC Raiders Error ART00004?

You open ARC Raiders, and suddenly ART00004 shows up. It stops you from logging in or joining a match.

What Is ARC Raiders Error ART00004

ART00004 is a connection and authentication error. It appears when the game client fails to communicate with the online servers from Embark Studios. When your device sends a login request, the server either does not respond or rejects the request because of a network issue, blocked connection, or temporary server problem.

The game depends on stable data exchange between your system, your internet connection, and the backend servers, so even a small break in that chain can trigger this error.

You usually see this error on the login screen, loading screen, or while matchmaking. It can appear on Steam, Epic Games, PlayStation Network, or Xbox Live. The message looks simple, but it points to a deeper connection failure between your device and the game servers.

Common Causes of ARC Raiders Error ART00004

This error can happen for several reasons, depending on your device, platform, or network setup.

  • Server downtime on Embark Studios due to maintenance or overload
  • Service issues on Steam or Epic Games
  • Weak or unstable internet causing packet loss
  • Incorrect DNS server settings blocking connection
  • VPN or proxy interfering with authentication
  • Corrupted game files or damaged cache data
  • Firewall or antivirus blocking network traffic

How to Fix ARC Raiders Error ART00004?

To resolve this issue efficiently, you need to check both your network and system settings. However, most fixes are simple and only take a few minutes.

Fix #1: Restart the Game and Device

This error often shows up because of temporary glitches. Restarting clears memory and resets the connection to the game servers.

Try these simple steps to quickly restart your system and game.

  1. Close ARC Raiders completely
  2. Restart your PC or console
  3. Launch the game again
  4. Wait for it to load fully
  5. Try logging in again

Fix #2: Check ARC Raiders Server Status

Sometimes the problem is not on your side. If Embark Studios servers are down, your game cannot connect no matter what you try. This can happen during updates, maintenance, or sudden traffic spikes when many players log in at once. In this case, waiting is the only real solution, and once the servers are stable, the error usually disappears on its own.

Fix #3: Verify Game Files

Corrupted files can break the connection between your game client and servers.

Follow the steps below to easily verify your game files.

  1. Open Steam or Epic Games
  2. Go to your game library
  3. Find ARC Raiders
  4. Open properties or settings
  5. Select verify or repair files
  6. Wait for the scan to finish

Fix #4: Restart Your Internet Router

A weak or unstable connection can stop your device from reaching the game servers. Restarting your router refreshes your network, clears temporary issues, and gives you a new connection path. Sometimes your internet looks fine, but small delays or packet loss can still cause problems, so a quick restart helps reset everything and improve stability.

Fix #5: Flush DNS Cache

Wrong DNS data can stop your system from finding the correct game server.

Here are the following steps which help you to flush DNS.

  1. Open Command Prompt on your PC
  2. Type ipconfig /flushdns
  3. Press Enter
  4. Wait for confirmation message
  5. Restart your system

Fix #6: Disable VPN or Proxy

VPN services can block or reroute your connection in a way that game servers do not accept. When you use a VPN, your traffic goes through a different region, which can confuse authentication systems or trigger security checks. Turning off the VPN helps your device connect directly to the official servers, which often fixes the error quickly.

Fix #7: Allow ARC Raiders Through Firewall

Firewall settings can block the game from accessing the internet.

Follow these easy instructions to allow the game through your firewall.

  1. Open Windows Security
  2. Go to Firewall settings
  3. Click Allow an app
  4. Find ARC Raiders
  5. Enable both private and public access
  6. Save changes

Fix #8: Reinstall ARC Raiders

If nothing works, the installation may be broken. Reinstalling the game removes corrupted files and installs a fresh version of the client. This helps fix deeper issues that simple repairs cannot solve. It takes more time, but in many cases, it clears persistent errors and restores proper connection with the servers.

Prevention Tips to Avoid ART00004 Error in Future

Taking a few preventive steps can help you avoid this error and enjoy smooth gameplay.

  • Keep ARC Raiders updated with latest patches
  • Use a stable internet connection
  • Restart your router regularly
  • Avoid VPN while gaming
  • Keep firewall settings correct
  • Verify game files after updates
  • Follow updates from Embark Studios

Conclusion

ART00004 is mainly a connection error that happens when your device cannot talk to the game servers. It often comes from network problems, server downtime, or corrupted files, and it can appear on platforms like Steam or Epic Games. The good thing is that most causes are simple and can be fixed without advanced knowledge.

Try each fix step by step and check what works for you. If the issue still stays, you may need to contact Embark Studios support for further help. And if this guide helped you, share it or drop a comment so others can fix the same problem faster.
