Help & Troubleshooting
Having trouble connecting to a XaelGaming server? Follow this checklist to resolve common client and network issues.
Pre-Flight Checklist
- Verify Server Address: Ensure the hostname is copied exactly with no leading/trailing spaces or unwanted port numbers.
- Check Exact Modpack Build: Modded servers require the specific version listed on their wiki page (e.g. ATMons 1.2.0, ATM10 8.0, ATM10 Sky 2.0.2, Cobblemon Lydu1ZNo, Prominence 3.9.27). A different version will fail with "Incompatible mod set".
- Allocate Adequate RAM:
- Vanilla / SMP: 2–4 GB
- Cobblemon / Whitelist SMP: 4–6 GB
- ATM10, ATMons, Prominence: 8–10 GB
- Restart Game & Launcher: Fully restart the launcher if assets or libraries fail to load.
