An error while debugging using QT Creator

Hi, Iam using Toradex Colibri VF61 as a part of my project. I followed the instructions that is given on your Website (link: “Qt Creator to cross compile - Embedded Linux” ). But while debugging the project i had received some errors which can be shown as
(" error: Could not connect to host: Host unreachable Is the device connected and set up for network access?"). Can you please provide me the reason and a viable solution for this. Expecting your reply

Please double check the ip address you’ve used and if you can ssh int it from your development machine.After you’ve verified the the ip address is correct and ssh works, you may try setting a password for a root user on the module, some versions of qtcreator doesn’t work with empty password.
