There are 2 possible reasons for such output:

   1. you are trying to run application without running/connected server.
   2. wrong server ip set in the web UI.

Things to fix: 1. check connection beetween kaa client & server then regenerate SDK.

Perform these two steps may be this can solve your problem.

  1. Just run this command on host machine

    sudo /usr/lib/kaa-sandbox/bin/change_kaa_host.sh $new host name/ip$

  2. Then change the IP address of using Admin UI, for that you need to sign in using username : kaa and passwword : kaa123

then go to setting > general setting then change the IP address preceded by :8080, enter your machine's public IP address, that can be easily accessible from anywhere.

Tips :: if you are using AWS instance then use public IP address of your instance.

Further error persist then drop your previous instance and launch a new instance.

For more details go the official documentation page

Hope it will be helpful for you.

I have configured my kaa's host name to be my current connection's ip address because i am using bridged adapter as one of my methods of getting the new host name

I had the same problem with KAA installation on my virtual server. Instead of putting the IP address inside kaa-node.properties just put the full domain name or hostname.

transport_public_interface=<server name or full domain name>

and on your client host, update DNS or /etc/hosts accordingly.

The client app will not complain about a name resolution issue.
