Bring the web server back online

Web & Deploy · medium · live throwaway Linux box · 3 tiered hints

The marketing site should be served by nginx on port 80 and return the exact body "tmpfs-academy OK" at GET /healthz. Right now the service is down and something in its configuration is wrong. Diagnose and fix it. Your fix must also survive a reboot — the service has to come back on its own. When you think it's solved, click "Check".

How it works

Press start and you get your own real, disposable Linux VM — in the browser terminal or over SSH. Work the task on a live system; tmpfs.tech grades your solution automatically against the actual machine state, then throws the box away. No install, free to try as a guest.
