Why can''t my friend join my Valheim server via IP address?

If your friend is unable to join your Valheim server via IP address, there are several potential issues to consider. Valheim''s multiplayer functionality relies on proper network configuration, server settings, and game version compatibility. The first step is to ensure that both you and your friend are running the same version of Valheim. Updates are frequent, and mismatched versions can prevent connections. Check the game version in the main menu and update if necessary.\n\nNext, verify that the server is correctly set up. If you''re hosting a dedicated server, ensure the server software is running and configured properly. For non-dedicated servers, make sure the host (you) has started the game in multiplayer mode and selected the correct world. If you''re using a dedicated server, double-check the server''s IP address and port settings. The default port for Valheim is 2456, but this can be changed in the server configuration file.\n\nFirewall and router settings are common culprits for connection issues. Both the host and the joining player need to ensure that Valheim is allowed through their firewalls. On Windows, this can be done by adding Valheim as an exception in the firewall settings. Additionally, the host''s router must have port forwarding enabled for the server''s port (default 2456). Without proper port forwarding, external players cannot connect to your server. Consult your router''s manual or online guides for instructions on setting up port forwarding.\n\nAnother potential issue is the use of a dynamic IP address. If your IP address changes frequently, your friend may be trying to connect to an outdated address. Consider using a static IP or a service like a Dynamic DNS (DDNS) to provide a consistent address for your server. Additionally, ensure that your friend is entering the IP address correctly, including the port number (e.g., 192.168.1.1:2456).\n\nIf all settings appear correct but the issue persists, try troubleshooting the connection. Have your friend ping your IP address to confirm they can reach your network. If the ping fails, there may be a network issue between your friend and your server. In such cases, using a VPN or a third-party server hosting service can sometimes resolve connectivity problems.\n\nFinally, consider the possibility of server overload or bugs. Valheim''s servers can struggle with high player counts or unstable connections. If you''re hosting a large server, try reducing the number of players or upgrading your hosting setup. For persistent issues, check the Valheim community forums or Discord for known bugs and workarounds.\n\nIn summary, ensure both players have the same game version, configure your server and network settings correctly, and troubleshoot connectivity issues step by step. With proper setup, you and your friend should be able to enjoy Valheim''s multiplayer adventures together.
