Valheim Server Manager for Windows
SupportedWindows · Cross-play relay
A dedicated Valheim server means your world lives on even when the host logs off. Gone Wrong Servers sets one up in minutes, keeps it patched on your terms, and protects your world file before anything risky happens.
If your clan already has a world, import it — Gone Wrong Servers manages the existing installation in place without moving or rewriting your saves.

Edition and cross-play
The -crossplay switch selects PlayFab relay, allowing supported-platform joins without router forwarding but preventing local-IP and loopback joining.
Mods and extensions
Valheim has no official mod support; every loader, server package and client dependency remains an unofficial compatibility and recovery decision.
Administration
Valheim uses case-sensitive platform IDs in text permission files and in-game admin commands; the official guide does not document native RCON.
Diagnose the exact symptom
Valheim troubleshooting
