Why can''t my friend see my Valheim server in the Steam list?

If your friend cannot see your Valheim server in the Steam list, there are several potential reasons and solutions to explore. Valheim''s multiplayer functionality relies on Steam''s networking features, and issues can arise from server settings, network configurations, or even Steam itself. Understanding the game mechanics and troubleshooting steps can help resolve the problem.\n\nFirst, ensure that your server is set up correctly. If you are hosting a dedicated server, make sure the server is running and accessible. For a dedicated server, you need to configure the server files properly, including the `start_headless_server.bat` file, and ensure the server is visible to the public. If you are hosting a non-dedicated server (where you play and host simultaneously), ensure that the game is set to ''Friends Only'' or ''Public'' in the server settings. This allows your friend to see the server in the Steam list.\n\nNext, check your network settings. Valheim uses Steam''s peer-to-peer networking, which requires proper port forwarding. If your router is not configured to allow traffic on the necessary ports (default is 2456-2458 for UDP), your server may not appear in the list. To fix this, log into your router''s settings and forward these ports to your PC''s local IP address. This ensures that external connections can reach your server. You can find detailed instructions for port forwarding on your router''s manufacturer website.\n\nAnother common issue is Steam''s server browser not updating properly. Sometimes, the Steam server list does not refresh automatically, making it difficult for your friend to find your server. To resolve this, ask your friend to manually refresh the server list by clicking the ''Refresh'' button in the Steam server browser. Alternatively, they can try joining directly via your Steam friend list by right-clicking your name and selecting ''Join Game.'' This bypasses the server list entirely.\n\nFirewall or antivirus software can also block Valheim''s connection. Ensure that both your and your friend''s firewalls allow Valheim and Steam through. On Windows, you can add exceptions for Valheim in the Windows Defender Firewall settings. Similarly, check your antivirus software to ensure it is not blocking the game. If you are unsure, temporarily disable the firewall or antivirus to test if it resolves the issue.\n\nIf the problem persists, verify that both you and your friend are using the same version of Valheim. Updates are frequent, and mismatched versions can prevent connections. Ensure both of you have the latest update installed by restarting Steam and checking for updates. Additionally, ensure that your Steam client is up to date, as outdated Steam versions can cause connectivity issues.\n\nFinally, if none of the above solutions work, consider using a third-party server hosting service. These services handle the technical aspects of server hosting, including port forwarding and server visibility, making it easier for your friend to join. Popular options include G-Portal, Survival Servers, and others. These services often provide a direct IP address or server name for your friend to connect to, bypassing Steam''s server list entirely.\n\nIn summary, troubleshooting server visibility in Valheim involves checking server settings, network configurations, Steam''s server browser, firewall settings, and game versions. By following these steps, you can resolve most issues and ensure your friend can join your server. If all else fails, third-party hosting services offer a reliable alternative.
