Fix Auth Test Game Matchmaking Issues

**Auth Test Game** has matchmaking or party-related issues. This is a *confirmed issue* with known solutions. Matchmaking problems are often server-side but can also be caused by NAT type restrictions, region settings, or party size limitations. **What's causing it:** • session sync delay (68% likely) • server overload (52% likely) Follow these steps to fix it: 1. increase timeout window. 2. retry handshake logic. 3. Check your NAT type — Strict/Type 3 NAT severely limits matchmaking. Enable UPnP in your router or forward game ports. 4. Try changing your server region in-game if available — some regions have longer queue times. 5. Restart the matchmaking if it takes longer than expected — backing out and re-queuing often helps.
