I have just updated my ePO from 18.104.22.1689 to ePolicy Orchestrator 5.3.2 (Build 156). I had my Agent Handlers running fine before this. Now when I try to upgrade, with the same details as I originally built them with with I keep getting the below.
Why isn't this working. DNS hasn't changed. I have tried the IP and still no dice. Both Agent Handler servers are giving the same popup.
