🚀 Start Here: Troubleshooting
Something not working? Don't worry — the large majority of issues are a connector that isn't fully seated, and you can fix them yourself in a few minutes. The universal first step for almost anything: power down, then unplug and firmly re-seat every connector, checking for bent pins and lining up the arrows on the Higo plugs.
