How do I troubleshoot the "Connection Lost" error during multiplayer gameplay?

The ''Connection Lost'' error in Valheim multiplayer can be frustrating, but it is often caused by issues with your internet connection, server settings, or game files. To troubleshoot this error, start by checking your internet connection. Ensure your Wi-Fi or Ethernet connection is stable and that other devices on your network are not consuming too much bandwidth. If you are hosting the server, make sure your upload speed is sufficient to handle multiple players. A minimum upload speed of 5 Mbps is recommended for a smooth multiplayer experience.\n\nNext, verify that the server settings are correct. If you are hosting a dedicated server, ensure the server is properly configured and that the port forwarding settings match the game''s requirements. Valheim uses port 2456-2458 by default, so make sure these ports are open on your router. If you are using a third-party hosting service, check their support documentation for any specific setup instructions. Incorrect server settings are a common cause of connection issues.\n\nIf the problem persists, check your game files for corruption. On Steam, you can verify the integrity of your game files by right-clicking Valheim in your library, selecting ''Properties,'' navigating to the ''Local Files'' tab, and clicking ''Verify Integrity of Game Files.'' This process will scan your game files and repair any corrupted or missing data. Corrupted files can cause connection issues, especially in multiplayer mode.\n\nAnother potential cause of the ''Connection Lost'' error is outdated mods. If you are using mods, ensure they are compatible with the current version of Valheim. Outdated or incompatible mods can disrupt multiplayer gameplay. Disable all mods temporarily to see if the issue resolves. If it does, re-enable them one by one to identify the problematic mod. Always download mods from trusted sources and keep them updated.\n\nIf you are playing on a shared server, ensure the server is not overloaded. Too many players or excessive activity in resource-intensive biomes like the Plains or Mistlands can strain the server. Consider limiting the number of players or reducing the complexity of your builds in these areas. Additionally, restart the server periodically to clear any accumulated lag or memory issues.\n\nFinally, if none of the above solutions work, try reinstalling the game. Backup your save files before doing so, as reinstalling will delete your local game data. Save files are typically located in the ''AppData\LocalLow\IronGate\Valheim'' folder on Windows. After reinstalling, restore your save files and test the connection again.\n\nTo prevent future connection issues, consider using a wired Ethernet connection instead of Wi-Fi, as it provides a more stable connection. If you frequently host multiplayer sessions, investing in a dedicated server or a reliable hosting service can improve performance. Regularly update your game and mods to ensure compatibility and stability. By following these steps, you can minimize the occurrence of the ''Connection Lost'' error and enjoy a smoother multiplayer experience in Valheim.
