How do I fix the "Server Offline" error when trying to connect?

The ''Server Offline'' error in Valheim is a common issue that can occur when trying to connect to a multiplayer server. This error typically indicates that the server is either not running, the connection details are incorrect, or there are network issues preventing access. To resolve this, you need to troubleshoot both the server setup and your local connection.\n\nFirst, ensure that the server is actually running. If you are hosting the server yourself, check that the Valheim Dedicated Server tool or the in-game hosting option is active. For dedicated servers, verify that the server process is running on your machine or hosting service. If you are using a third-party hosting service, log in to their control panel to confirm the server status. Sometimes, servers may go offline due to maintenance or crashes, so restarting the server can often resolve the issue.\n\nNext, double-check the server connection details. If you are joining a friend''s server, ensure that you have the correct IP address, port number, and password (if applicable). For dedicated servers, the IP address and port must match the server''s configuration. If you are unsure, ask the server host to confirm the details. Note that Valheim uses UDP ports 2456-2458 by default, so ensure these ports are open on both the server and your local network.\n\nNetwork issues can also cause the ''Server Offline'' error. If you are playing on a local network, ensure that your router is configured to allow traffic on the required ports. For external connections, check that your internet connection is stable and that there are no firewall or antivirus programs blocking Valheim. You can test your connection by pinging the server''s IP address or using online tools to check port availability.\n\nIf the server is running and the connection details are correct, the issue may lie with the game files or server configuration. Verify the integrity of your Valheim game files through Steam by right-clicking on Valheim in your library, selecting ''Properties,'' then ''Local Files,'' and clicking ''Verify Integrity of Game Files.'' For dedicated servers, ensure that the server configuration files (such as ''start_headless_server.bat'') are correctly set up and that the server is updated to the latest version of Valheim.\n\nAnother common cause of the ''Server Offline'' error is mods. If you or the server host are using mods, ensure that all players have the same mods installed and that they are compatible with the current version of Valheim. Mismatched or outdated mods can cause connection issues. If you suspect mods are the problem, try connecting to the server without any mods enabled.\n\nFinally, if none of the above solutions work, consider restarting your computer and router. Sometimes, a simple reboot can resolve network or software glitches. If you are still unable to connect, try joining a different server to determine if the issue is specific to the server or your setup. For persistent problems, consult the Valheim community forums or Discord for additional support.\n\nIn summary, fixing the ''Server Offline'' error involves checking the server status, verifying connection details, troubleshooting network issues, and ensuring game files and mods are up to date. By following these steps, you can quickly identify and resolve the issue, allowing you to enjoy Valheim''s multiplayer experience with your fellow Vikings.
