Suggested Solution
Configure an inbound Windows firewall rule to allow incoming access to port 40705. This could be accomplished by running this command line on the target server:
netsh advfirewall firewall add rule name="ControlUp Agent" dir=in action=allow protocol=TCP localport=40705
Alternatively, you can automate this task by configuring the “Define inbound port exceptions” GPO setting and adding the following value: “40705:tcp:localsubnet:enabled:ControlUp-Agent”
