What is ARMR0002? (Matchmaking Failed / Breakout Error)
ARMR0002 (also called "Breakout" error code) is a matchmaking handshake failure between the ARC Raiders client and Embark Studios servers. This error occurs when you try to join a match and the initial connection handshake fails, preventing matchmaking from working.
Common Symptoms:
- Matchmaking fails immediately when trying to queue
- Error message: "Matchmaking Failed" or "ARMR0002"
- Cannot join games or find matches
- Connection timeout during matchmaking
Root Causes:
- DDoS Mitigations: Embark's servers may be under attack, causing connection filtering during matchmaking
- Local DNS Cache Issues: Your computer may be using stale DNS records that block the matchmaking handshake
- Network Configuration: Firewall or router settings blocking the matchmaking connection
- Server Overload: High player counts during peak times causing matchmaking failures
