What causes the "Server Disconnected" error, and how do I fix it?

The ''Server Disconnected'' error in Valheim is a common multiplayer issue that can disrupt gameplay and frustrate players. This error typically occurs when the connection between the player and the server is interrupted, either due to network issues, server configuration problems, or game bugs. Understanding the root causes and implementing practical solutions can help you get back to exploring the biomes and building your Viking legacy.\n\nOne of the primary causes of the ''Server Disconnected'' error is unstable internet connectivity. Valheim requires a stable and strong connection to maintain multiplayer sessions. If your internet connection is weak or frequently drops, the game will disconnect you from the server. To fix this, ensure your router is functioning properly and consider using a wired connection instead of Wi-Fi for better stability. Additionally, check for background applications consuming bandwidth, such as streaming services or downloads, and close them to prioritize Valheim''s connection.\n\nAnother common cause is server-side issues. If you''re playing on a dedicated server, the server may crash or experience downtime due to high player loads or technical problems. In this case, restarting the server often resolves the issue. For self-hosted servers, ensure your server software is up to date and compatible with the latest Valheim version. If you''re using a third-party hosting service, contact their support team to check for server outages or configuration errors.\n\nGame version mismatches can also trigger the ''Server Disconnected'' error. Valheim frequently receives updates, and if the server and client versions don''t match, players may be unable to connect. To fix this, ensure both the server and all players have updated their game to the latest version. On Steam, you can verify the integrity of game files by right-clicking Valheim in your library, selecting ''Properties,'' and navigating to the ''Local Files'' tab. Click ''Verify Integrity of Game Files'' to ensure no files are corrupted or missing.\n\nFirewall or antivirus settings can sometimes block Valheim''s connection to the server. To resolve this, add Valheim as an exception in your firewall or antivirus software. On Windows, you can do this by navigating to ''Windows Security,'' selecting ''Firewall & Network Protection,'' and clicking ''Allow an app through firewall.'' From there, ensure Valheim is checked for both private and public networks. If you''re using a third-party antivirus, consult its documentation for instructions on adding exceptions.\n\nFor players experiencing persistent issues, port forwarding may be necessary. Valheim uses specific ports (2456-2458 by default) for multiplayer connections. If these ports are blocked by your router, you''ll need to forward them. Access your router''s settings (usually through a web browser) and locate the port forwarding section. Enter the required ports and your server''s IP address, then save the changes. This process varies by router model, so consult your router''s manual for detailed instructions.\n\nFinally, if none of the above solutions work, consider reinstalling Valheim. Corrupted game files or installation errors can cause connectivity issues. Uninstall the game through Steam, delete any remaining files in the installation directory, and reinstall it. This ensures a clean installation and often resolves persistent problems.\n\nTo prevent future disconnections, regularly update your game and server software, maintain a stable internet connection, and monitor your network for potential issues. By following these steps, you can minimize the ''Server Disconnected'' error and enjoy uninterrupted multiplayer adventures in Valheim.
