I think the issue is that you are behind the proxy which in which case you need to write a manual configuration in Docker systemd service file. That will override the default docker.service file.

If you are using Docker for Windows, then simply set the default DNS to 8.8.8.8 on the "vEthernet (DockerNAT)" network adapter. But remember, this is not the best practice as you will be exposing from your office network.

In linux environment, you could add the environment variable as you are behind HTTP_PROXY or HTTPS_PROXY, as you are using port 80 or 443 respectively. As shown below in /etc/systemd/system/docker.service.d/http-proxy.conf

[Service]
Environment="HTTP_PROXY=http://proxy.example.com:80/"

as for HTTTP_PROXY in /etc/systemd/system/docker.service.d/https-proxy.conf

[Service]
Environment="HTTPS_PROXY=https://proxy.example.com:443/"

Then just restart docker after deamon reload:

 $ sudo systemctl daemon-reload
$ sudo systemctl restart docker

Hope this works.

I was facing the same issue when trying to build or pull an image with Docker on Win10. Changing the DNS of the Docker vEthernet(DockerNAT) network adapter to 8.8.8.8 fixed it for me, as described in this GitHub issue.

To change the DNS go to Docker (TrayIcon) -> Settings -> Resources -> Network and set a fixed DNS server ip = 8.8.8.8.

Changing the DNS server in the configuration of the windows network adapter worked too.

After restarting Docker is able to pull and build images again.

This may be the old one, but fixed available here

I had the same issue and only found out after 30 minutes that I was on a VPN network for work which blocks other sites. I went off the VPN, and it worked :) This is definitely a network issue. When it said "not authenticated", I thought perhaps I needed some login credentials or so.

I had the same problem and the following fix has worked for me: https://github.com/moby/moby/issues/22635#issuecomment-260063252

In my case I've added the following 2 nameserver lines to /etc/resolv.conf file.

before:

nameserver 127.0.0.53

after:

nameserver 8.8.8.8
nameserver 8.8.4.4
nameserver 127.0.0.53

For my case, my company needed to define my IP in the White list in order to access the cloud.docker files. So do not hesitate to tell the responsible person if you have such error.

I face this problem when performing Ansible AWX installation.

I had my own private DNS :192.168.0.254 & 192.168.0.253 but was receiving same error.

Issue got resolved after change my DNS back to 8.8.8.8 & 8.8.4.4.

I have same issue with registry deployed in swarm. Restart docker helps but after some time it occurs again.

Redeploy registry with docker-compose 

sudo docker-compose up -d

and all works fine

I have faced this error sometimes, my docker image is built smoothly before but when I have to remove all images ( even I do not make any change with the docker configuration files or any error in code). this still happens.

so I think that it may cause by the connection for it does a "Get https://registry-1.docker.io/v2/:....."

I have change DNS to google DNS 8.8.8.8 and 8.8.4.4 then it 's worked. good luck!

I faced this issue on ubuntu when I am trying to build elasticsearch:

And I got this error:

ERROR: Get https://docker.elastic.co/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

It was my network connection problem. I was using VPN. so I disconnect my VPN connection and it's working fine.

for some reasons, it's trying to look up the domain it seems trying to search for the domain inside the local network after I disconnect the VPN everything worked fine.

I got this error from my own Internet connection. Switched to another provider, all good.

On Mac OS X, I fixed this issue by not using the experimental virtualization framework.

Preferences -> Experimental Features

小开

This error occurs on Big Sur 11.3.1, Intel when you check the box for "Use new virtualization framework" under the Experimental Features tab. Unchecking the box and restarting Docker fixed this problem for me.

My issue was with Windows WSL, not only do you have to set the static dns servers as mentioned above in both the Docker Desktop client, and your containers, but you also need to add

 [network]
generateResolvConf = false

to the /etc/wsl.conf in your linux containers. You will need to reboot your container as outlined in https://superuser.com/questions/1126721/rebooting-ubuntu-on-windows-without-rebooting-windows, or you can reboot your pc.

I got the same error and it was resolved by

docker logout registry-1.docker.io

Windows 10 - home PC. none of the solution worked for me. what worked is un-install docker, restart PC, "run as administrator" while installing exe. worked!!

小开

None of those solutions worked for me. I finally make it work simply by doing an update of docker. (MAC OS)

I experienced this issue when trying to push to Docker.

  1. I updated Docker Desktop (via the GUI)

  2. I also ran docker system prune which prompts:

    WARNING! This will remove: - all stopped containers - all volumes not used by at least one container - all networks not used by at least one container - all dangling images

Confirm this by entering yes

I also had problems with pull requests timing out. with both

docker pull hello-world
kubeadm config images pull

Perhaps this problem started for me when upgrading the VM from ubuntu 18 to 20, but there were also many kubernetes related config changes I made, so not sure.

anyway this solution resolved it for me.

thanks @nils!

incase the above link brakes, here is a quote:

I had the same issue yesterday. Since I am behind a company proxy, I had to define the http-proxy for the docker daemon in:

/etc/systemd/system/docker.service.d/http-proxy.conf

The problem was, that I misconfigured the https_proxy, how it is described here. I used https:// in the https_proxy environment variable, which caused this error.

This configuration works for me:

cat /etc/systemd/system/docker.service.d/http-proxy.conf


[Service]
Environment=http_proxy=http://IP:PORT/
Environment=no_proxy=localhost,127.0.0.1
Environment=https_proxy=http://IP:PORT/

Remember that you have to restart the docker daemon after changing this configuration. You can achieve this by using:

systemctl daemon-reload
systemctl restart docker

It could be temporary network issue. I had same issue. I would these two

  • Re-run the command again
  • Restart the Docker Desktop
小开

I had the same issue. I was getting this error while following the Udemy course. Since I was new to Docker I was actually building image by giving incorrect repository name( I was using Instructor username instead of mine docker repository username). When we push the image to Docker hub, use your docker repository name. Hence build image using your username.

docker build . -t docker_username/example:latest

where . represent current directory where your Dockerfile resides. Please first logged in your docker repository by using Docker desktop in your system

Hope this will solve someone's problem.

Just add at the end of your shell command --dns 8.8.8.8

Check in case VPN is blocking..

my solution was :

docker image prune and docker volume prune

Experienced this Error while I was trying to : docker pull odoo

Just log in through the terminal and use the below command

I was stuck too, tried everything I could then I tried these: https://fedingo.com/how-to-uninstall-docker-in-ubuntu/

Make sure you repeat step 1 and 2 mentioned in link untill step 1 shows nothing

then procceed with step 3 and the next steps

then delete docker folder from here

/etc/systemd/system/docker.service.d/

then follow :

https://docs.docker.com/engine/install/ubuntu/

I was getting the same error. I am using a ubuntu 20.04 system

Error response from daemon: Get "https://registry-1.docker.io/v2/": net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

I added the missing lines inside /etc/resolv.conf

nameserver 8.8.8.8
nameserver 8.8.4.4

sudo nano /etc/resolv.conf

This is how it looks now.

nameserver 8.8.8.8
nameserver 8.8.4.4
nameserver 127.0.0.53
options edns0 trust-ad
