Reynald	Hi, On your screenshot, sys/tg_test/1 Tango device is marked as exported but it cannot be contacted. Several possible reasons: TangoTest/test instance crashed. Please check that there is a TangoTest/test process running on 172.16.248.135 with PID 9832. If not, restart the device server. Your client application cannot access the host and port where your TangoTest instance is running 172.16.248.135:40287 (Network/ firewall issue) Hoping this helps, Reynald Rosenberg's Law: Software is easy to make, except when you want it to do something new. Corollary: The only software that's worth making is software that does something new.

Reynald	On your screenshot, jive is reporting that TangoTest/test device server process was running on a computer having IP address 172.16.248.135 and with the PID (Process ID) 9832. So you just need to log on computer having IP address 172.16.248.135 and see whether there is a process running with this PID 9832. Do you know the computer having this IP address 172.16.248.135. This should be the computer on which you started TangoTest device server Is this computer a Linux computer or Windows computer? On Linux, you can use the following command to check whether there is a process running with PID 9832: `ps -ef \| grep 9832 \| grep -v grep` On Windows, you can use the task manager, select the "Processes" tab and add PID (Process Identifier) column from the "View->Select columns…" menu and check whether there is a process with PID 9832. Good luck! Rosenberg's Law: Software is easy to make, except when you want it to do something new. Corollary: The only software that's worth making is software that does something new.
