No Online Devices Found

This issue occurs when the discovered Sonos devices do not report as online.
Issue(s)
The Crestron Home system was able to discover Sonos devices but is unable connect to any of
the devices for setup.

Explanation
After a successful Sonos discovery scan, the Crestron Home system selects one of the Sonos
devices as the primary device. The system then connects to the device and subscribes for the
Favorites event (used to retrieve and update the Favorites list) and the Group Configuration
event (used to retrieve and update the group and player configuration).
If one of these three processes fails, the Crestron Home system assumes that the device is
offline and moves to the next Sonos device that was discovered. If one of these three processes
fails for all discovered Sonos devices, the Sonos system cannot be created, and a "No Online
Devices Found" error is raised. The Crestron Home system provides a notification of this issue on
the Diagnostics screen.

Diagnostics Screen - No Online Devices Found

Tap the gear icon next to the Sonos System gateway to view the Sonos System Settings page
with the About tab open by default. A "No Online Devices Found" status is indicated for System
Connection Failure Reason.
