How do I troubleshoot the "Connection Timed Out" error?

The ''Connection Timed Out'' error in Valheim is a common multiplayer issue that can disrupt your Viking adventures. This error typically occurs when the game client cannot establish a stable connection to the server, often due to network issues, server settings, or game version mismatches. Understanding the game mechanics and troubleshooting steps can help you resolve this issue and get back to exploring biomes like the Meadows, Black Forest, or even the treacherous Swamp.\n\nFirst, ensure that both the host and all players are running the same version of Valheim. Game updates are frequent, and version mismatches can cause connection problems. To check your game version, open the Steam client, navigate to your library, and verify that Valheim is up to date. If updates are available, install them before attempting to reconnect. This step is crucial for maintaining compatibility between players.\n\nNext, verify your network connection. A stable internet connection is essential for multiplayer gameplay. Test your connection by visiting a website or running a speed test. If your connection is unstable, try restarting your router or switching to a wired connection for better reliability. For players hosting a server, ensure that your network allows for port forwarding. Valheim uses port 2456-2458 by default, so configure your router to forward these ports to your hosting device.\n\nIf you''re using a dedicated server, check the server settings. The server configuration file (start_headless_server.bat or similar) must include the correct IP address and port settings. Additionally, ensure that the server is not overloaded with too many players or mods, as this can cause timeouts. For example, if you''re hosting a server for 10 players but have 15 attempting to join, the server may struggle to maintain connections.\n\nFirewall and antivirus software can also interfere with Valheim''s multiplayer functionality. Ensure that Valheim is added to the exception list in your firewall and antivirus settings. On Windows, you can do this by navigating to the Windows Defender Firewall settings and allowing Valheim through both private and public networks. Similarly, check your antivirus software for any blocked applications and add Valheim to the allowed list.\n\nIf the issue persists, consider using a VPN. Sometimes, regional network restrictions or ISP throttling can cause connection problems. A VPN can help bypass these restrictions by masking your IP address and routing your connection through a different server. However, ensure that the VPN server you choose has low latency to avoid introducing additional delays.\n\nFor players experiencing persistent issues, switching to a different server type may help. If you''re using a peer-to-peer connection, try switching to a dedicated server or vice versa. Dedicated servers often provide more stable connections, especially for larger groups. You can rent a dedicated server from a hosting provider or set one up yourself using tools like Valheim Dedicated Server.\n\nFinally, if none of the above solutions work, consider reinstalling Valheim. Corrupted game files can cause connection issues, and a fresh install can resolve these problems. Before reinstalling, back up your save files located in the AppData/LocalLow/IronGate/Valheim folder to avoid losing progress.\n\nIn summary, troubleshooting the ''Connection Timed Out'' error involves checking game versions, verifying network stability, configuring server settings, adjusting firewall and antivirus settings, and considering alternative server types. By following these steps, you can resolve connection issues and continue your Viking journey with friends. Remember, a stable connection is key to enjoying Valheim''s multiplayer experience, whether you''re building a base in the Meadows or battling trolls in the Black Forest.
