Wiping an Astroneer server deletes its current data so it can start again. This is not a selective player reset, so create a working backup first if you may need the existing save.
- Open your Astroneer server in the control panel.
- Create a backup and wait for it to finish, then stop the server.
- Click Wipe Server.
- Read the deletion warning, tick Are you sure? and click Execute.

- Wait for the wipe task to finish, then start the server.
- Join and confirm that a fresh game is created.
If you only want to roll back recent progress, restore a backup instead of wiping the server.
