Updated 8 Feb 2020 – Updated UMS KB Article, Updated Firewall Rule info
Issue:
Scanning for new thin clients discovers the available thin clients, select ‘Include’ to bring the device into Universal Management Suite (UMS).
During the inclusion process it fails with the error:
“ERROR: Cannot connect to remote management server”.
Reason:
Communication between UMS server and thin client requires port 30001 to be open on the server running IGEL UMS. This is visible in the Windows Firewall log file (C:\Windows\System32\LogFiles\Firewall\pfirewall.log) if ‘Log dropped packets’ is enabled.
Solutions:
- Allow the following ports on the Windows Firewall
- Incoming Rule: 30001
- Outgoing Rule: 30005

- Disable Windows Firewall

Good post, it is what I was looking for.
To check it from the Endpoint-site you can use the probeport-command:
probeport IP-ADDRESS OF UMS PORT
Results are
connection refused
connection successful
like:
probeport 192.168.1.50 9080
do this for the ports
80
443
8443
9080
30001
30005
Additional hint:
When connecting via a Firewall which does interception the UMS recognise this and brings up an error as well – so be sure to exclude the interception on the FW
Happy IGELing!
