The WhatsApp channel connection has expired or was revoked
Why it happens
Meta refused the access token saved for this channel because it is invalid, has expired or was revoked (for example after a Facebook password change or removed permissions). Messages cannot leave this channel until it is connected again. Meta’s full message is in the technical details.
What to do
Open the WhatsApp channel settings in Rabt and choose “Reconnect”, then complete the Meta connection steps again and approve every permission requested.
