sync failover issue

Time is realy important so check the time and set NTP if you can. Also check the ConfSync IP's on each system, I would also set this to be the HA VLAN and IP addresses, this can be done under the following on both systems: Device Management, Devices, , Device Connetiviy, ConfSync

Do the same for the Network Failover under: Device Management, Devices, , Device Connetiviy, Network Failover (delete all but the HA VLAN IPs)

Go back and try to do the initial sync if that works you can then test network failover.
