# Offline and session expired

> What the offline banner, the session-expired overlay and the idle lock mean, and what to do.

| You see | What it means | What to do |
| - | - | - |
| An offline banner at the top | Your device lost its connection. | Wait for it to reconnect. PHB tells you when you're back. |
| The `/offline` page | You opened a page while offline. | Reconnect and reload. |
| **You're offline — changes won't save** (notification settings) | Changes can't be saved offline. | Reconnect first. |
| Clinical Tools offline notice | Calculators still work offline. | Carry on. |
| A **Sign in again** overlay | Your session ended. | Sign in. PHB returns you to the page you were on. |
| The patient app locked | You were idle. | Sign in again. |
| **Your session has expired.** on a nursing page | Your session ended. | Sign in again at `/hospital/login`. |

## Will I lose my work?

* Doctor notes save automatically as you type.
* Some forms, such as desk registration, keep a draft on this device.
* Drafts on the device are cleared when you sign out.
* PHB doesn't save new records offline. Make sure you are online before you save.

<Note>
  PHB only retries a failed save when it is safe to do so. If a save fails, check your connection and try again. Don't double-click.
