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

If your friend cannot see your Valheim server in the server list, there are several potential reasons and solutions to explore. Valheim''s multiplayer functionality relies on proper server setup, network configuration, and game settings. Understanding these mechanics is crucial for troubleshooting and ensuring a smooth multiplayer experience.\n\nFirst, ensure that your server is set up correctly. If you are hosting a dedicated server, make sure the server software is running and configured properly. For example, if you are using the Valheim Dedicated Server tool, verify that the server is online and that the necessary ports (2456-2458 UDP) are forwarded on your router. Without proper port forwarding, your server will not be visible to external players. Check your router settings and ensure that the IP address of your hosting machine is correctly assigned.\n\nIf you are hosting a non-dedicated server (i.e., playing and hosting simultaneously), ensure that your game is set to ''Start Server'' and not ''Friends Only'' or ''Invite Only.'' These settings can restrict visibility. Additionally, make sure your friend is using the correct version of Valheim. If one of you has an outdated version, the server may not appear in the list. Update the game through your platform (Steam, Xbox, etc.) to ensure compatibility.\n\nNetwork issues can also prevent your server from appearing. If you are using a VPN, disable it, as VPNs can interfere with server visibility. Similarly, check your firewall settings to ensure Valheim and its server software are allowed through. Both Windows Firewall and third-party antivirus programs can block the necessary connections. Add exceptions for Valheim in your firewall settings to resolve this.\n\nAnother common issue is the use of mods. If you or your friend have installed mods, they may cause compatibility problems. For example, mods that alter server settings or networking can prevent the server from appearing in the list. Try disabling mods temporarily to see if this resolves the issue. If the server becomes visible, identify the problematic mod and either remove it or ensure both players have the same mods installed.\n\nIf your server still does not appear, consider using the ''Join IP'' feature. Share your server''s IP address with your friend and have them manually connect by entering the IP in the ''Join IP'' field. This bypasses the server list and directly connects to your server. To find your IP address, use a service like ''WhatIsMyIP.com'' or check your router''s settings. Note that this method requires your friend to enter the correct IP and port (e.g., 192.168.1.1:2456).\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, such as port forwarding and network configuration, making it easier for your friend to join. Popular options include G-Portal, Survival Servers, and Host Havoc. These services often provide a control panel for managing your server and ensuring it is visible to all players.\n\nIn summary, troubleshooting server visibility in Valheim involves checking server settings, network configuration, game versions, mods, and firewall rules. By following these steps, you can resolve most issues and ensure your friend can join your server. Remember to communicate with your friend throughout the process to confirm when the server becomes visible or if additional steps are needed.
