In Device Management >> Devices >> [self device] > Failover Network. Address Family Mode resets back to "IPv4 & IPv6" instead of already set configuration i.e. IPv4 when a new peer unit is added.


Inconsistent configuration


-- Add a new device into the device trust. -- Set both devices to "IPv4". -- Join the devices in device trust.


Modify the address family to IPv4 manually after adding the peer.
