Suggested Solution
Configure an inbound Windows firewall rule to allow incoming access to port 40705. You can do this with PowerShell:
New-NetFirewallRule -DisplayName "ControlUp Agent Port" -Direction Inbound -LocalPort 40705 -Protocol TCP -Action Allow
Alternatively, you can automate this task by configuring the “Define inbound port exceptions” GPO setting and adding the following value: “40705:tcp:*:enabled:ControlUp-Agent”
