Hi,
When High Availability (HA) is configured and two internet connections are in use, in the event of one of the internet connections becoming unavailable, it is possible to receive a notification.
To achieve this, in the WebUI go to 'Logs and Monitoring' > Notification > Setting > Enable the checkboxes labeled 'Primary Internet is down' and 'Primary Internet restored'.
Notifications are directed to the email platform exclusively when the severity of the notification is classified as a 'Security Alert.' In this particular case, the severity of the notification is categorized as an 'Informative Event.' Consequently, notifications of this type will be delivered to mobile devices but not sent to email addresses.
