Troubleshooting Multiplayer Connection Issues

To diagnose your multiplayer problem, I need specifics. Please provide:

• Game title: (e.g., Minecraft, Fortnite, Call of Duty: Warzone)
• Platform: PC, Xbox, PlayStation, Switch, Mobile?
• Exact error message / code: (e.g., "Connection timed out," "NAT Type Strict," "0x80070435")
• What you've tried: Restart router? Wired vs. Wi-Fi? Port forwarding? Different account?
• Play context: Private match with friends? Public matchmaking? Cross-play?

The more detail you share, the more targeted the fix—whether it's NAT configuration, server status, firewall rules, or a known game-specific bug.
