Hi,

 

Is the health check failing on all devices in the Device Group, or just the new one?

 

Is there a firewall between F5 and backend servers? The health check is done form the self-IP of a device, so maybe the new device IP is not configured in that firewall rule base.

 

Did you check with tcpdump to see any traffic leaving the F5?
