You open ARC Raiders, and ART00004 shows up. It stops you from logging in or starting a match.
When this happens, the game can’t connect to Embark Studios servers, but sometimes your own network causes it too. This guide explains what the error means, why it happens, how to fix it step by step, and how to avoid it later.
What Is ARC Raiders Error ART00004?
ART00004 is a connection and authentication error. It appears when your game client fails to communicate with the servers managed by Embark Studios. When you launch the game, your system sends a login request, but the server may not respond correctly due to network issues, server downtime, or blocked traffic.
The multiplayer system depends on a stable connection between your device, your internet connection, and the game servers, so even small issues like packet loss, DNS failure, or timeout can trigger this error.
You usually see this error on the login screen, loading screen, or matchmaking. It can appear on Steam, Epic Games, PlayStation Network, or Xbox Live. The message looks simple, but it points to a deeper connection problem between your system and the servers.
Common Causes of ARC Raiders Error ART00004
This error can happen for several reasons depending on your system and network setup.
- Server downtime or maintenance from Embark Studios
- Platform issues on Steam or Epic Games
- Weak or unstable internet connection causing packet loss
- Incorrect DNS settings blocking server communication
- VPN or proxy interfering with authentication requests
- Corrupted game files or cache data
- Firewall or antivirus blocking network access
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 appears due to temporary glitches. Restarting clears memory and refreshes your connection to the servers.
Try these simple steps to quickly restart your system and game.
- Close ARC Raiders completely
- Restart your PC or console
- Launch the game again
- Wait until it fully loads
- Try logging in
Fix #2: Check Server Status
Sometimes the issue 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 or high player traffic. In such cases, waiting is the only option, and once servers are stable, the error usually disappears.
Fix #3: Verify Game Files
Corrupted files can break communication between your system and servers.
Follow the steps below to easily verify your game files.
- Open Steam or Epic Games
- Go to your library
- Select ARC Raiders
- Open properties or settings
- Click verify or repair
- Wait for completion
Fix #4: Restart Your Internet Router
A weak or unstable connection can stop your system from reaching the servers. Restarting your router refreshes your network, clears small connection issues, and improves stability. Even if your internet seems fine, hidden delays or packet loss can still cause problems, so this step often helps.
Fix #5: Flush DNS Cache
Incorrect DNS data can prevent your system from finding the correct server.
Here are the following steps which help you to flush DNS.
- Open Command Prompt
- Type ipconfig /flushdns
- Press Enter
- Wait for confirmation
- Restart your system
Fix #6: Disable VPN or Proxy
VPN services can redirect your connection through different regions, which may conflict with server authentication systems. When this happens, the server may reject your request. Turning off the VPN allows your system to connect directly to the official servers, which often fixes the issue 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.
- Open Windows Security
- Go to Firewall settings
- Click Allow an app
- Find ARC Raiders
- Enable access on private and public networks
- Save changes
Fix #8: Reinstall ARC Raiders
If the problem continues, the installation may be corrupted. Reinstalling removes damaged files and installs a fresh version of the game. This helps fix deeper issues and ensures your game client works properly with the servers.
Is ART00004 a Server Issue or Your Problem?
In most cases, this error comes from server-side problems. When Embark Studios servers are overloaded or under maintenance, they cannot respond to all player requests. This leads to connection failure even if your system works fine. It is common during updates or peak hours when many players are online, so the issue is often temporary.
However, sometimes the issue can come from your side. Network instability, blocked connections, or corrupted files can also trigger the error. That’s why it is important to try basic fixes before assuming it is only a server problem.
Prevention Tips to Avoid ART00004
Taking a few simple steps can help you avoid this error in the future.
- Keep ARC Raiders updated
- Use a stable internet connection
- Restart your router regularly
- Avoid VPN while gaming
- Keep firewall settings properly configured
- Verify game files after updates
- Follow updates from Embark Studios
Conclusion
ART00004 is mainly a connection error that happens when your device cannot communicate with the game servers. It is often caused by server downtime, network problems, 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 with basic troubleshooting steps.
