How do I fix the "World Not Found" error in Valheim multiplayer?

The ''World Not Found'' error in Valheim multiplayer is a common issue that can occur when trying to join a server or load a shared world. This error typically happens due to mismatched world files, server configuration issues, or connectivity problems. Understanding the game mechanics and following a systematic troubleshooting approach can help resolve this issue.\n\nFirst, ensure that the world you are trying to join exists and is correctly named. If you are hosting a server, double-check that the world file is saved in the correct directory. On Windows, Valheim world files are stored in ''C:\Users\[YourUsername]\AppData\LocalLow\IronGate\Valheim\worlds''. If the world file is missing or corrupted, the game will not be able to load it, resulting in the ''World Not Found'' error.\n\nIf you are joining a friend''s server, confirm that the host has the correct world selected and that the server is running. The host should ensure that the server is set to ''Community'' or ''Friends Only'' in the server settings, depending on who is allowed to join. Additionally, both the host and players should ensure that their game versions are up to date, as version mismatches can cause compatibility issues.\n\nAnother common cause of the ''World Not Found'' error is incorrect server IP or port settings. If you are using a dedicated server, verify that the IP address and port number are correctly entered in the server configuration file. For example, the ''start_headless_server.bat'' file should include the correct IP and port, such as ''valheim_server -nographics -batchmode -name MyServer -port 2456 -world MyWorld -password MyPassword''. If the port is blocked by a firewall or router, players will be unable to connect.\n\nIf the issue persists, try restarting both the server and the game. Sometimes, temporary glitches can cause the ''World Not Found'' error. Additionally, ensure that all players have a stable internet connection. Poor connectivity can lead to failed world loading attempts. If you are using mods, disable them temporarily to rule out conflicts. Some mods may interfere with world loading or multiplayer functionality.\n\nFor advanced troubleshooting, consider using a backup of the world file. If the world file is corrupted, replacing it with a backup can resolve the issue. To create a backup, simply copy the world files from the ''worlds'' directory to a safe location. If the error occurs after a game update, check the Valheim community forums or Discord for known issues and patches. Developers often release hotfixes for common problems.\n\nFinally, if you are still unable to resolve the ''World Not Found'' error, consider creating a new world and transferring your progress. While this may seem like a last resort, it can be a practical solution if the original world file is irreparably corrupted. Use console commands or mods to quickly rebuild your base and recover lost items. For example, the ''devcommands'' console command can spawn items and structures, speeding up the recovery process.\n\nIn summary, the ''World Not Found'' error in Valheim multiplayer can be resolved by verifying world files, ensuring correct server settings, updating the game, and troubleshooting connectivity issues. By following these steps, you can minimize downtime and get back to exploring the biomes, crafting powerful items, and battling formidable foes with your fellow Vikings.
