Reconnect tills and branch screens

Branch devices need local connectivity as well as valid activation. Working internet does not prove that tills, kitchen screens and phones can reach one another.

Check the LAN

1. Confirm all devices belong to the same TableTop branch.
2. Connect them to the same reachable router network.
3. Avoid guest Wi-Fi isolation or separated networks that block device traffic.
4. On Windows, allow the TableTop apps through the firewall on the trusted private network.
5. Check the leader is running and retry LAN discovery.
6. Verify the QR address still points to the intended main till.

Local services use separate ports for cashier, kitchen, notifier and discovery. Have the network administrator check application rules if devices remain unreachable.

Record which devices can reach which peers before requesting help. Check a wired connection too if Wi-Fi traffic is isolated by the router.
