🎮 Game Error Codes What it means & how to fix it

ARC Raiders Error Codes

ARC Raiders is an online extraction shooter, so most of its errors are connection codes: AREX for in-raid disconnects and packet loss, ARMR for matchmaking failures, and ARAV when your PC's security settings block the game. Wi-Fi packet loss and Easy Anti-Cheat are the two biggest culprits. Here's what each code family means and the fixes that get you back into a raid.

Error codes

AREX0024 (Heartbeat Failure) Connection lost mid-raid — the server stopped receiving data from your client

Cause: Packet loss or a brief connection drop, most common on Wi-Fi, so the server times out your client.

Fix:
  1. Switch from Wi-Fi to a wired Ethernet connection to eliminate packet loss.
  2. Restart your router and PC, then flush DNS (ipconfig /flushdns).
  3. Disable any VPN and check for ISP throttling during peak hours.
AREX (connection errors, general) A connection error between your client and the raid server

Cause: Unstable route, NAT/firewall interference, or a server-side hiccup.

Fix:
  1. Set DNS to 8.8.8.8 / 8.8.4.4 or 1.1.1.1 and reset your network stack (netsh winsock reset).
  2. Consider port forwarding if you're behind a strict NAT.
  3. Check the ARC Raiders server status before assuming a local fault.
ARMR0002 (Matchmaking failure) The matchmaking service is up but can't place you into a lobby instance

Cause: Usually a game version mismatch, or the matchmaker can't find/assign a specific instance.

Fix:
  1. Fully update the game so your client version matches the servers, then restart it.
  2. Restart the matchmaking by returning to the main menu and requeueing.
  3. Verify game files on Steam to rule out a partial/failed update.
ARAV (system integrity errors) Your PC's security settings are blocking the game from running

Cause: Anti-cheat requirements (Secure Boot / TPM) or antivirus blocking Easy Anti-Cheat.

Fix:
  1. Whitelist ARC Raiders and Easy Anti-Cheat in Windows Defender / your antivirus.
  2. Ensure Secure Boot and TPM 2.0 are enabled if the anti-cheat requires them.
  3. Reinstall Easy Anti-Cheat from the game's install folder, then relaunch.

Fixes that work for most ARC Raiders (PC / Xbox / PlayStation) errors

  1. Verify/repair the game files (Steam: Properties -> Installed Files -> Verify integrity; EA App/Epic: Manage -> Repair/Verify) — this replaces corrupted files behind most crashes and connection faults.
  2. Update your GPU driver with a clean install (use DDU), and install the latest Microsoft Visual C++ Redistributables (x86 and x64) plus the DirectX End-User Runtime — missing runtimes and stale drivers cause most launch crashes.
  3. Flush your DNS and reset the network stack (ipconfig /flushdns; netsh winsock reset), switch to Google (8.8.8.8) or Cloudflare (1.1.1.1) DNS, and prefer a wired connection over Wi-Fi to cut packet loss.
  4. Disable overlays (Steam, Discord, GeForce Experience) and any VPN, and add the game and its launcher to your firewall and antivirus exceptions.
  5. Check the game's official server/status channels before assuming a local problem — many named connection errors are a maintenance window or outage and clear on their own.

FAQ

What does ARC Raiders error AREX0024 mean?

AREX0024 is a 'Heartbeat Failure' — the server stopped receiving data from your client for too long and dropped the connection. It's most common on Wi-Fi due to packet loss. Switch to a wired Ethernet connection, restart your router, disable any VPN, and check for ISP throttling.

How do I fix ARC Raiders matchmaking error ARMR0002?

ARMR0002 usually means a version mismatch — the matchmaker is live but can't place your client. Fully update the game so it matches the server version, restart it, and verify the game files on Steam. Requeue from the main menu if it repeats.
