Hi @annielee That really looks like an issue with the management interface and the HA setup, the daemon is trying to allocate the IP to make the request from to the socket but cannot, the only thing I can think is that when you do the test authentication it is actually sourced from the local box you are on at the time. You could check at the RADIUS end to see which IP is being presented as the client when the test succeeds, if that is the case it could well be an issue with floating IP allocation for the Active/Active HA to communicate to the RADIUS server, I am not really used to Active Active deployments but thought I would suggest that anyway. Hope you get it worked out!
