CRITICAL FIX: Your Windows System Time must be perfectly synced. Go to Settings > Time & Language > Date & time > Click 'Sync now'. Even a 2-minute offset causes JWT validation to fail.

Port Forwarding Required: Hytale uses QUIC over UDP port 5520. Ensure your router forwards UDP 5520 to your PC. In Windows PowerShell (Admin), run: `New-NetFirewallRule -DisplayName "Hytale UDP" -Direction Inbound -Protocol UDP -LocalPort 5520 -Action Allow`

Try these steps:

1. Restart your router

2. Disable VPN if using one

3. Check if your firewall is blocking Hytale

4. Try connecting during off-peak hours
