Windrose Server Won’t Start / Illegal Instruction

Checklist

1. Read the first console error after Start.
2. Confirm SteamCMD download finished (App ID for Windrose server).
3. Restore ServerDescription.json if recently edited.
4. Verify disk space and RAM tier vs crew size.
5. As a last resort, reinstall the egg after backups.

Managed Chapter22 notes: hosts are chosen for the Wine/Unreal egg path — “illegal instruction” reports are more common on mismatched DIY VMs than on our game nodes.

Frequently Asked Questions

Illegal instruction in a home VM?

Some Unreal/Wine builds need specific CPU flags. Chapter22 managed hosts are sized for the egg — home VMs may differ.

First place to look?

Pterodactyl console for the first exception.

Reinstall egg?

Backup worlds + ServerDescription.json first.

Need help?

If you are stuck after following this guide, open a ticket from the Chapter22 client area with the exact error, the port or DNS change you made, and whether the service listens locally (ss / Resource Monitor) but fails externally.
