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.

It's been a long time and I can't remember what solution exactly solved the problem because I usually try so many things in my bid to troubleshoot. However, there are standard procedures to follow. Please check this guide:

and this too

If the DSC config steps are followed strictly, it should be fine. Watch out specifically for the DEVICE GROUP NAME. It must be the same on all the cluster members. Watchout also for the ConfigSync address/interface and the HA vlan set ( It is "internal" vlan by default if you choose to use existing vlan and not create a separate HA vlan).

 

Goodluck!
