IGEL OS devices shown as offline in UMS while they are actually online?


I have a few devices which are shown as offline in UMS while they are actually online and can be reached from UMS (Send Message, Reboot). In the information tool there’s a green ✔️ for UMS server. The device is on the same network as the UMS, so no firewall is active. What can cause this?


If you ping the devices from UMS, which network latency (ping response time) do you get?


Like 2ms.

Now I rebooted it and it’s online. But I have some machines that are nearly never shown as online.


UDP 30005 from UMS to endpoint not filtered by an AV, Switch DoS or Software Firewall?


No, I don’t think so. I was happy to have a device right on front of me on my desk so I can do some experimentation. 😉 But now it’s online… And the other devices are in use. 🙂
