Che fails to communicate with Workspace agent

Hi, I’m have eclipse che running natively on a CentOS 7 instance at google cloud platform. I’m able to get che interface on my browser, but cannot start a project.

from my che.properties file

machine.docker.local_node_host=172.17.0.1
api.endpoint=http://_my instance external IP_:${SERVER_PORT}/ide/api

from my /etc/hosts (putted manualy): 172.17.0.1 che-host

installed Docker as pre-requirement Docker version 1.10.3, build 20f81dd

from my ~/.bash_profile file

export JAVA_HOME=/usr/lib/jvm/jre-1.8.0-openjdk-1.8.0.77-0.b03.el7_2.x86_64
export CHE_HOME=/opt/eclipse-che-4.1.0
export CHE_LOCAL_CONF_DIR=$CHE_HOME/conf
export CHE_DOCKER_MACHINE_HOST=172.17.0.1

ifconfig output

this happens in Starting workspace agent stage, after below stages

I’m happy to say the issue was finally resolved, the problem was with opening the firewall ports in the gcloud network assigned to my instances, beside of an instance FW there is a virtual network FW that gcloud provides. using: gcloud compute firewall-rules create docker-range --allow tcp:32768-65535 there is an option to set IP restriction as well.

Thanks eivantsov -I learned allot from this thread. excited to start using Che keep up the good work !
