Device Shows Peer (synced) as "Offline"

I have sync-failover configured among three devices. They are all in sync but one of them shows the peers as "Offline". What could the problem be? Thank you.

Be sure to follow the Device Service Clustering (DSC) troubleshooting guide. There are a few reasons this happens, usually fairly easy to resolve.

 

Things you will want to check include making sure that in the Device list, that each device has the information for each other device. If a device is not showing up correctly, you will want to start there. You must have the device certificates for each unit imported into the sister units. The Device Group must be configured identically on all devices.

If all else fails, you may want to start at the beginning and reset the peering relationship between all of the units.
