may be you are behind a firewall/proxy server i was also behind my office firewall so i tried below steps which resolved this issue.

For setting up proxy for docker, please do the following:

1. Create a systemd drop-in directory for the docker service: $ mkdir -p /etc/systemd/system/docker.service.d $ vim /etc/systemd/system/docker.service.d/http-proxy.conf Then add below content with proxy settings with it

[Service] Environment=“HTTP_PROXY=http://<allowed_proxy_ipv4_address>:<proxy_port_num>/”

1. For HTTPS proxy server: $ vim /etc/systemd/system/docker.service.d/https-proxy.conf Then add below content with proxy settings with it

[Service] Environment=“HTTPS_PROXY=https://<allowed_proxy_ipv4_address>:<proxy_port_num>/”

1. Flush changes execute: $ sudo systemctl daemon-reload

2. Restart Docker: $ sudo systemctl restart docker

3. Verify that the configuration has been loaded: $ systemctl show --property=Environment docker

IIRC there were some cases where DNS resolution failed on Docker for Mac, depending on the DNS server that was configured on the host;

Can you try if it works if you set 8.8.8.8 as DNS server in the daemon configuration? You can set this by providing a JSON configuration in the preference panel (under daemon -> advanced), e.g;

{ "dns" : [ "8.8.8.8", "8.8.4.4" ]}

I had same issue while setting up dockers for first time ever and tried on two Ubuntu Server (16.04.3 Xenial) VM’s in home network with same problem with pulling HELLO-WORLD image after fresh installing and after few days for digging in much promised post for setting proxy in home NETWORK and none of these works

setup proxing in home network where no proxy has been setup 😃, linux or windows or mac, proxy is same accross everywhere like internet 😃

#curl https://registry-1.docker.io/v2/ to see can get respose and setup credentials…

Hello from Docker!

I had this issue caused by a bad login being saved.

docker logout fixed it

Started having this issue after upgrading the version. Resolved for me by logging out of DockerHub

docker pull hello-world.

I got this…

Error response from daemon: Get https://registry-1.docker.io/v2/: dial tcp: lookup registry-1.docker.io on [::1]:53: rea d udp [::1]:41859->[::1]:53: read: connection refused

I fixed it by quitting Docker from the tray, then simply restarting it.

To resolve this issue just restart your docker machine

command: docker-machine restart

It worked for me.

Had this issue on ubuntu 14.04. Running the command sudo service docker restart worked for me

so many but not a single right one. people are answering without any understanding of the issue

Hm, no direct suggestions, but does look like a networking error in your setup

ping @djs55 any suggestions, or known issues on our side?

Restarting docker resolved issue
