What causes the "Server Not Found" error in Valheim multiplayer?

The ''Server Not Found'' error in Valheim multiplayer is a common issue that can stem from several causes, including network problems, server configuration issues, or game version mismatches. Understanding the game mechanics and troubleshooting steps is essential for resolving this error and ensuring a smooth multiplayer experience.\n\nFirst, ensure that both the host and the players are using the same version of Valheim. The game frequently receives updates, and if one player is on an outdated version, they won''t be able to connect to the server. To check your game version, open the Steam client, navigate to your library, right-click on Valheim, and select ''Properties.'' Under the ''Updates'' tab, verify that the game is set to update automatically. If not, manually update the game before attempting to connect.\n\nAnother common cause of the ''Server Not Found'' error is network connectivity issues. Valheim multiplayer relies on a stable internet connection, and any disruptions can prevent players from finding the server. Start by checking your internet connection on both the host and player devices. Run a speed test to ensure your connection meets the minimum requirements for online gaming. If the connection is unstable, try restarting your router or switching to a wired connection for better stability.\n\nFirewall and antivirus settings can also block Valheim''s multiplayer functionality. Ensure that Valheim is added to the list of allowed applications in your firewall and antivirus software. On Windows, navigate to ''Windows Security,'' select ''Firewall & Network Protection,'' and click ''Allow an app through firewall.'' Add Valheim to the list if it isn''t already there. Similarly, check your antivirus settings to ensure Valheim isn''t being blocked.\n\nIf you''re hosting a dedicated server, ensure that the server is properly configured and running. Dedicated servers require specific port forwarding settings to allow external connections. The default ports for Valheim are 2456-2458 (TCP/UDP). Log in to your router''s admin panel and forward these ports to the IP address of the server machine. Additionally, verify that the server is online and accessible by checking the server logs or using a port-checking tool.\n\nFor players using the in-game server browser, the ''Server Not Found'' error can occur if the server isn''t listed or the IP address is incorrect. Double-check the server''s IP address and ensure it''s entered correctly. If the server is password-protected, confirm that the correct password is being used. Alternatively, try joining through Steam by selecting ''Join Game'' from your friend''s profile if they are hosting the server.\n\nFinally, if none of the above solutions work, consider restarting both the game and the server. Sometimes, a simple restart can resolve temporary glitches or connectivity issues. If the problem persists, consult the Valheim community forums or support channels for additional assistance.\n\nPractical tips for avoiding the ''Server Not Found'' error include keeping your game updated, maintaining a stable internet connection, and ensuring proper server configuration. By following these steps, you can minimize disruptions and enjoy a seamless multiplayer experience in Valheim.
