Longvinter problems are almost always the config file. Work through these in order.
1. The setting reverts after a restart
- Stop the server before editing. Longvinter writes its config on shutdown, so edits made while it runs are overwritten.
- Wait for the panel to report the server is offline, not just that you clicked stop.
- Save the file, then start the server.
2. The setting is ignored
- Each setting has to be under its own section header in
Game.ini. The server identity and the gameplay rules live under different headers, and a line under the wrong one is skipped with no error. - Check for a typo in the setting name. Unknown names are ignored.
- Read the console during boot for the values the server actually loaded.
3. The password does not work
- Longvinter accepts letters and numbers in the password. Anything else can stop it working.
- Check for a trailing space.
- Restart after changing it.
4. The server is not in the browser
- Give it a few minutes after a start.
- Check
ServerNameis set and distinctive enough to search for. - Have a player try a direct join with
IP:Portto prove the server itself is reachable.
5. Players are refused
- Check
MaxPlayers. - Restart the server after a game update so it matches the clients.
- A player on an older build cannot join.
6. The island lost progress
- The world is written on a clean shutdown. Use Stop rather than Kill.
- Download a copy of the save folder from the Files tab before any large change.
Open a ticket from Support in the Client Area with the last 50 lines of console output if none of this fits.
