AUTH101: Session expired
What this means
Your session ended and you need to sign in again.
Sign in again to carry on. Anything you had already saved stays on the till and is sent for you once you are back in.
Your data
No order or product data is affected. A sale you saved while the session was out is held on the device, not lost, and goes to your store by itself after you sign in.
Troubleshoot
- Sign in again when prompted. A sale that was waiting sends itself — you do not need to re-enter it or press Save again. To watch it go, open Health, then Database.
- If the same order is still listed as waiting several minutes after you signed in, use Send again on its row in Health, then Database.
- Frequent expiries (several per day) usually come from the site: a security plugin shortening session lifetimes or clearing tokens. Ask the site administrator which security plugins run on the store, and to check WP Admin, then POS, then Logs — a refused sign-in is recorded there with its reason.
