Numbers can drop offline if the phone loses internet, the WhatsApp account is unlinked, or the device sleeps for a long time. Reconnecting takes about a minute.

Before you start

  • Identified which connection is offline (the connections list and the layout banner both show it)
  • The phone with that WhatsApp number, online and unlocked

Steps

1

Open Connections

Navigate to the connections module.
2

Find the disconnected number

It is marked with a disconnected status.
3

Click Reconnect

A new QR appears.
4

Scan with WhatsApp

Same flow as initial pairing - Settings -> Linked Devices -> Link a Device.
5

Wait for confirmation

Status flips back to connected.

Tips

  • Most disconnects come from the phone losing internet or someone manually unlinking the device in WhatsApp.
  • Until the number is reconnected, any chats that arrive on it are not visible in the inbox.
