Working on a new HA server, and running the installer from my main poller on the HA server. I've disabled A/V, I've ensured ports are open, but every time I run the installer it fails with "We are unable to download file UpgradeFix.exe from main server. Please check connection to main server and try again." Not sure how to move forward. I can browse to the main server and get to that installer without issue. My initial HA server did not have this problem, but the new server won't complete these install. This is holding up trying to get SolarWinds setup into a DR configuration. Has anyone run into this before and found a way around it?
