You're offline.

The Huiyu Pi server is unreachable. The agent runs against your code on the server, so there's no useful offline mode — sessions, file edits, and terminals all need a live connection.

• If the server is on your laptop, check it's still running.
• If it's behind a reverse proxy, check the proxy is up.
• If you're on a flaky network, try reconnecting.

This page is served by the cached service worker. Once the server responds again, normal navigation resumes on the next reload.
