Why can''t my friend join my Valheim server after a restart?

If your friend cannot join your Valheim server after a restart, the issue is often related to server settings, connectivity, or game updates. Valheim''s multiplayer functionality relies on proper server configuration and stable internet connections. When a server restarts, certain settings or updates may disrupt the connection process, preventing players from joining. Below, we’ll explore the most common causes and provide step-by-step solutions to resolve the issue.\n\nFirst, ensure that the server is running correctly after the restart. If you’re hosting a dedicated server, check the server logs for any error messages. These logs can provide clues about what went wrong during the restart. For example, if the server failed to load the world file, your friend won’t be able to connect. In this case, verify that the world file is intact and located in the correct directory. If you’re using a hosting service, contact their support team to confirm the server is online and functioning.\n\nNext, check your firewall and port forwarding settings. Valheim requires specific ports (2456-2458 by default) to be open for multiplayer connections. If these ports are blocked or misconfigured, your friend won’t be able to join. To fix this, ensure that your router is forwarding the correct ports to your server’s IP address. You can test the connection using online port-checking tools to confirm the ports are open. If you’re unsure how to configure port forwarding, consult your router’s manual or search for guides specific to your model.\n\nAnother common issue is mismatched game versions. Valheim frequently receives updates, and if your server is running an older version than your friend’s game, they won’t be able to join. To resolve this, ensure both the server and your friend’s game are updated to the latest version. Steam usually updates games automatically, but you can manually check for updates by right-clicking Valheim in your library, selecting Properties, and navigating to the Updates tab. If you’re using a dedicated server, update it by downloading the latest server files from SteamCMD.\n\nIf the server is running and the versions match, the issue might be related to the server password or visibility settings. Valheim servers can be set to public or private, and private servers require a password to join. Double-check that your friend is entering the correct password and that the server is set to private if you want to restrict access. Additionally, ensure the server name is unique and doesn’t conflict with other servers, as this can cause confusion when trying to connect.\n\nFinally, consider using a third-party server hosting service if you’re experiencing persistent issues. These services handle server maintenance, updates, and connectivity, reducing the burden on you as the host. Popular options include G-Portal, Survival Servers, and Nitrado. These platforms often provide user-friendly interfaces and 24/7 support, making it easier to manage your Valheim server.\n\nIn summary, troubleshooting multiplayer issues in Valheim requires checking server logs, verifying port settings, ensuring game versions match, and confirming server visibility and password settings. By following these steps, you can resolve most connectivity problems and get back to exploring the biomes with your friends. Remember to keep your game and server updated, and consider using a hosting service for a smoother multiplayer experience.
