IGEL UMS – “Error: Cannot connect to remote management server”

Published by Carl Behrent – 8 Feb 2019

Updated 10 Oct 2019 – Updated UMS Registration URL for UMS 6.02

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.

  1. Good post, it is what I was looking for.

  2. 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!

    Cheers
