⚠️ Common CS2 Error Codes
VAC Authentication Error
VAC could not verify your game session. Restart Steam, verify game files, or run Steam as administrator.

How CS2 Matchmaking Works
When you queue for a match, CS2's matchmaking system (known as the Game Coordinator or GC) performs several steps to find you the best possible game:
Queue Entry: Your skill group, Prime status, and trust factor are evaluated
Player Matching: The system searches for players with similar skill levels and ping preferences
Server Selection: A game server in the optimal datacenter is reserved for your match
Connection: All players connect directly to the game server via Valve's relay network

Close bandwidth-heavy apps (streaming, downloads) while playing
Add Steam and CS2 as firewall exceptions to prevent connection blocks
