Understanding the Root Causes

From my analysis of player reports and official documentation, the AREX0003 error stems from several potential causes:

Primary Causes:

1. Server-Side Issues – Authentication server overload during peak hours
2. Network Configuration Problems – DNS resolution failures
3. Local Network Instability – Packet loss or connection interruptions
4. Security Software Interference – Firewall/antivirus blocking game traffic
5. Outdated Network Drivers – Incompatible or corrupted drivers

Platform-Specific Observations:

• PC Players: Most affected, especially those using Ethernet connections
• Console Players: Rarely affected, suggesting PC-specific configuration issues
• Geographic Variation: Some regions experience higher rates due to routing issues

Frequently Asked Questions

Is AREX0003 a permanent ban?

No. AREX0003 is purely a technical connection error. If you were banned, you would receive a different, specific message regarding account suspension.

Why does the error only happen during peak hours?

When thousands of players try to log in simultaneously, the authentication servers can become overwhelmed. This “server strain” is a common cause of AREX0003, and in this case, the only fix is to wait until traffic subsides.

Does changing DNS really help?

Yes, many players report success switching to public DNS servers like Google (8.8.8.8) or Cloudflare (1.1.1.1). This helps if your ISP’s default DNS struggles to resolve the game’s server addresses.

Should I use Ethernet or Wi-Fi?

Counterintuitively, some players fix the issue by switching FROM Ethernet TO Wi-Fi. This appears related to different DNS configurations between connection types. Test both to see what works for your setup.

How long does this error typically last?

With proper troubleshooting, most players resolve the issue within 30 minutes. Server-related instances typically resolve within a few hours as traffic normalizes.

Technical Deep Dive: Understanding AREX0003

For technically-inclined players, here’s what’s happening under the hood:

Network Flow Analysis:

Normal Connection:

Client → DNS Resolution → Auth Server → Game Server → Success

AREX0003 Error:

Client → DNS Resolution → [Timeout/Failure] → AREX0003 Error

Common Failure Points:

1. DNS Resolution Timeout – Your ISP’s DNS can’t resolve game server addresses
2. Authentication Server Response – Server overload prevents proper handshake
3. Packet Loss – Network instability drops critical connection packets
4. Firewall Interference – Security software blocks necessary ports/protocols

Future Outlook

Arc Raiders is currently in Early Access, and Embark Studios is actively working on stability improvements. Based on patch note analysis:

• Connection stability is a priority focus
• Server infrastructure improvements are ongoing
• Error handling is being refined for better user experience

Players can expect gradual improvement in connection reliability as the game approaches full release.
