I've installed docker, jenkins and docker-build-step in jenkins.
I've set an step in order to build an image from a Dockerfile of my repository.
It dumps me this message:

EDIT This is my docker.service configuration file related with connection:
ExecStart=/usr/bin/docker daemon -H fd:// -H tcp://127.0.0.1:4243 -H unix:///var/run/docker.sock Docker is listening to:
netstat -tupln | grep 4243 tcp 0 0 127.0.0.1:4243 0.0.0.0:* LISTEN I've gone on Docker Builder configuration and I've set up Docker URL to http://127.0.0.1:4243. Test connection tells me:
Something went wrong, cannot connect to tcp://127.0.0.1:4243, cause: null I've also made an request to the API REST using this command curl -XGET http://localhost:4243/containers/json and the results is right:

The message is exactly the same despite of I've specified the uri:
