How do I fix the "Server Not Responding" error when hosting a game?

The ''Server Not Responding'' error in Valheim is a common issue when hosting multiplayer games, often caused by connectivity problems, server settings, or technical glitches. To fix this, start by ensuring your game and Steam client are updated to the latest version. Outdated software can lead to compatibility issues, especially when hosting or joining multiplayer sessions. Check for updates in Steam by navigating to your library, right-clicking Valheim, and selecting ''Properties'' to verify game files.\n\nNext, confirm that your internet connection is stable. A weak or unstable connection can cause the server to drop or fail to respond. Test your connection by running a speed test or playing other online games to rule out broader network issues. If your connection is unstable, consider restarting your router or switching to a wired connection for better stability.\n\nIf your connection is stable, check your server settings. When hosting a game, ensure you select ''Start Server'' instead of ''Start Game'' in the Valheim menu. Starting a server allows other players to join your world, while starting a game only creates a local session. Additionally, make sure your server is set to ''Community'' or ''Friends Only'' if you want to restrict access. Public servers can sometimes attract unwanted traffic, leading to performance issues.\n\nPort forwarding is another critical step for hosting a multiplayer server. Valheim uses specific ports (2456-2458) to communicate between players. If these ports are not open on your router, other players may not be able to connect. To forward ports, access your router''s settings (usually through a web browser) and create a rule to allow traffic on ports 2456-2458 for both TCP and UDP protocols. Consult your router''s manual or online guides for specific instructions.\n\nFirewall and antivirus software can also block Valheim''s connection. Ensure Valheim is added to your firewall''s exception list and that your antivirus is not interfering with the game. On Windows, you can do this by navigating to ''Windows Security'' > ''Firewall & Network Protection'' > ''Allow an app through firewall'' and adding Valheim to the list.\n\nIf the issue persists, try restarting your computer and Steam client. Sometimes, temporary glitches can cause the ''Server Not Responding'' error, and a simple restart can resolve the problem. Additionally, consider using a dedicated server tool for Valheim, which provides more control over server settings and can improve stability. The dedicated server tool is available in your Steam library under ''Tools'' and requires some setup but offers a more reliable hosting experience.\n\nFinally, if none of the above solutions work, check Valheim''s official forums or community Discord for updates on server issues. Occasionally, the problem may be on the game''s end, and developers may release patches or workarounds. By following these steps, you should be able to resolve the ''Server Not Responding'' error and enjoy a smooth multiplayer experience in Valheim.
